My call, in one breath: Sabki nazar GPUs (NVIDIA) pe hai. Lekin asli bottleneck ab chip ke andar aur chip-to-chip data move karna hai — aur copper apni limit pe pahunch chuka hai. Iska solution hai silicon photonics: copper ki jagah light (photons) se data bhejna, seedha silicon chip pe. Jab har bada data centre AI ke liye ban raha hai, to ye tech "optional" nahi — compulsory ban rahi hai.
My bet: agle 1–2 saal me silicon photonics + optical interconnect ka ek "quiet boom" aayega, aur isme lead kar rahi kuch fundamentally strong US aur Indian companies multibagger ban sakti hain. Yeh page us thesis ka timestamp hai. Koi tumhe seedhe nahi batayega — par khichdi yahीं pak rahi hai.
Main koi SEBI/SEC-registered advisor nahi hoon. Main ek founder hoon jo technology trends aur market behaviour ko obsessively track karta hai. Ye blog "tips" nahi — ye mera research-backed nazariya hai, public aur dated. Jaise maine gold-silver-crypto wali prediction likhi thi, waise hi yeh bhi record pe ja raha hai.
Aur main ye bhi clearly likh deta hoon: ye sab foreign + small-cap exposure wala high-risk zone hai. Pehle poora padho, samjho, phir apna research karo. Chalo deep dive karte hain.
Pehle — Silicon Photonics Hai Kya? (Simple Bhasha Me)
Aapke laptop, phone, data centre — sab ke andar data electrons (copper wires) ke through travel karta hai. Problem: jaise-jaise data bahut zyada aur bahut fast hota hai, copper garam hone lagta hai, signal kharab hone lagta hai, aur bijli (power) bahut zyada lagti hai. Ek limit ke baad copper aage nahi ja sakta — isse engineers "copper wall" bolte hain.
Silicon photonics ka idea simple hai: electrons ki jagah light (photons) use karo data bhejne ke liye — woh bhi seedha silicon chip ke upar, regular chip manufacturing process me hi. Light se data bhejne ke fayde:
- Bahut zyada speed/bandwidth — light se ek hi waqt me kai gunaa zyada data.
- Kam power + kam heat — long distance pe photons electrons se kahीं efficient.
- Distance ka problem nahi — copper kuch cm me weak ho jaata hai; light meters/kilometres easily.
Fibre-optic cable to humne saalon se internet me dekha hai (light se data, lambi doori). Silicon photonics us tech ko chip ke andar, micro-level pe le aata hai. Yahi reason hai ki ise "future of fibre cable" bolna galat nahi — ye fibre ki taqat ko seedha processor ke paas le jaata hai.
Ye Boom Kyun, Aur Kyun ABHI?
Ek line me: AI data centres. Jab GPT-jaise models train aur run hote hain, to hazaaron GPUs ko aapas me baat karni padti hai — massive amount of data, super-fast, lagataar. Ye "interconnect" (chips ko jodने wala layer) ab sabse bada bottleneck ban gaya hai. GPU kitna bhi powerful ho, agar data time pe nahi pahuncha to woh idle baithta hai — aur idle GPU = jala hua paisa.
Isiliye industry tezi se "co-packaged optics" (CPO) ki taraf badh rahi hai — yaani optical engine ko seedha switch/GPU package ke andar baitha dena, taaki data light se move ho, copper se nahi. NVIDIA ne khud apne future networking switches me silicon photonics / co-packaged optics ka direction announce kiya hai. Jab industry ka sabse bada player is direction me jaata hai, to poori supply chain ko follow karna padta hai.
Mera point: jab tak data centre ban rahe hain (aur ye to abhi shuruaat hai), silicon photonics + optical interconnect ki demand sabse zyada badhne wali hai. Ye "nice to have" se "must have" ban chuki hai. Aur jab demand structural hoti hai, tab leading companies multi-year tailwind pe hoti hain.
Kyun Koi Seedha Nahi Bata Raha (The "Khichdi")
Ye part important hai. Silicon photonics consumer-facing nahi hai — koi iPhone jaisa product nahi jo aapko dikhe. Ye B2B, infrastructure-layer tech hai jo data centre ke andar chhupi hoti hai. Media aur retail ka poora dhyaan GPUs (NVIDIA) pe hai, kyunki woh "face" hai. Lekin har GPU ko data feed karne wali optical plumbing — uspe spotlight bahut kam hai.
Yahi hota hai har bade tech cycle me: jab gold rush chalta hai, to sona dhoondne wale (GPUs) headlines me hote hain — par lambi race me "picks & shovels" bechne wale (optical components, manufacturing) bhi quietly fortune banate hain. Silicon photonics us picks-and-shovels layer ka naya, under-the-radar version hai. Jab tak ye "mainstream story" banegi, tab tak shuruaati move ho chuka hoga.
Ek Aasan Analogy — Taaki Picture Clear Ho Jaaye
Socho ek bahut badi office building hai (= AI data centre), jisme hazaaron log (= GPUs) kaam kar rahe hain aur unhe ek doosre tak constant messages bhejni hain. Abhi tak ye messages chhote tube me ball daal ke (= electrons in copper) bheji ja rahi thi. Jab log kam the, theek tha. Par ab building me lakhon log aa gaye, aur tube garam ho rahe hain, jaam ho rahe hain, aur AC ka bill (= power) phat raha hai.
Silicon photonics ka matlab hai — ab message roshni ki kiran (laser) se bhejo, seedha har desk ke paas optical "pipe" laga ke. Light garam nahi hoti, jaam nahi hoti, aur ek hi pipe me ek saath hazaaron messages alag-alag colours me ja sakti hain. Isse building 10x zyada efficient ho jaati hai. Jo company ye "light pipes" aur unke laser-engines banaati hai — woh is poori building boom ki silent supplier hai. Bas yahi hai poora thesis, ek line me: jab building (data centre) ban rahi ho, light-pipe banane wala kabhi bhookha nahi rahega.
The US Leaders — Jo Iss Tech Ko Drive Kar Rahe Hain
Yahan main companies ko 3 buckets me baant raha hoon. Yeh buy/sell recommendation NAHI hai — ye sirf "kaun is space me kaam kar raha hai" ka educational map hai. Har naam ke saath apna research zaroor karna.
🟦 Bucket 1: Core Optical Leaders
- Coherent (COHR) — lasers + optical components + datacom transceivers ka bada player. AI data-centre optics demand ka seedha beneficiary. Vertically integrated (indium phosphide se le ke modules tak).
- Lumentum (LITE) — optical components & lasers; cloud/datacenter transceivers me growing exposure. Photonics ka pure-ish play.
- Marvell (MRVL) — custom AI silicon + electro-optics & optical DSPs (Inphi acquisition ke through). Co-packaged optics roadmap me central. Ye "silicon + photonics dono" wala rare combo hai.
- Broadcom (AVGO) — networking switches (Tomahawk/Jericho) + co-packaged optics initiatives. Mega-cap, par optical interconnect shift ka direct gatekeeper.
🟩 Bucket 2: Picks & Shovels (Sabse Underrated)
- Fabrinet (FN) — ye mera favourite "behind the scenes" naam hai. Ye optical modules ka contract manufacturer hai — matlab kai badi companies (optical transceivers, photonics modules) inse banwati hain. Jo bhi jeete, manufacturer ko order milta hai. Classic picks-and-shovels.
- Cisco (CSCO) — Acacia (coherent optics) aur Luxtera (silicon photonics) ko acquire kar chuka hai. Ek sleeping giant jiske paas serious photonics IP hai.
- NVIDIA (NVDA) — directly photonics company nahi, par demand ka engine. Inke silicon-photonics / co-packaged-optics networking roadmap se poori supply chain ko fuel milta hai. Indirect, par foundational.
- GlobalFoundries (GFS) — silicon photonics foundry (chip banane wali factory) jiske paas dedicated photonics platform hai. "Factory layer" ka exposure.
🟥 Bucket 3: High-Risk, High-Reward Small/Mid Caps
⚠️ Ye sabse speculative bucket hai — yahan multibagger ban sakta hai, par zero bhi ho sakta hai. Sirf woh paisa jo aap kho sakte ho.
- POET Technologies (POET) — optical interposer ka pure-play small-cap. Agar inki tech mainstream adoption pakad le, to leverage bada hai; par execution & funding risk bhi utna hi.
- Credo Technology (CRDO) — high-speed connectivity (active electrical/optical cables). Interconnect bottleneck ka adjacent play.
- Applied Optoelectronics (AAOI) — datacenter optical transceivers; highly volatile, but data-centre optics cycle me leveraged.
The India Angle — Honest Picture
Yahan main bilkul seedhi baat karunga, kyunki yahीं log galti karte hain. India me abhi koi bada pure silicon-photonics chip wala public company nahi hai — ye chip-level tech mostly US/Taiwan ke paas hai. Lekin iska matlab ye nahi ki Indian investor ke liye kuch nahi. India ka asli leverage optical fibre + networking + data-centre infrastructure me hai — jo isi AI/data wave pe ride karta hai:
- Sterlite Technologies (STL) — India ki sabse badi optical fibre & cable company. Data explosion = fibre demand. Silicon photonics chip nahi banati, par "light-based data" ecosystem ki backbone supplier hai.
- HFCL Ltd — optical fibre cable + telecom & networking equipment. 5G + fibre + data-centre connectivity ka India play.
- Tejas Networks (Tata Group) — optical & data networking equipment. Tata ke semiconductor + networking ambitions ke saath ye ek strategic long-term naam hai.
Aur ek aur layer — data centre buildout in India. Jaise-jaise India me hyperscale data centres ban rahe hain, fibre, networking gear, aur (eventually) advanced optics ki demand structurally badhegi. Plus, India ke semiconductor mission me aage chal ke photonics packaging bhi aa sakta hai. Mera maanna: India ka 1–2 saal ka direct play silicon photonics chip nahi, balki uske aas-paas ka fibre + networking infra hai. Isiliye main inhe alag bucket me rakhta hoon — same wave, alag risk profile.
8 Criteria — Jinki Wajah Se Is Thesis Me Dum Hai
Ek thesis tabhi serious hai jab uske peeche structural reasons hon. Yahan mere 8 angles:
- 1. Copper wall real hai. Physics ki limit hai — high speed pe copper garam, weak, power-hungry ho jaata hai. Optical iska seedha jawab hai. Ye fashion nahi, engineering necessity hai.
- 2. Bandwidth demand exponential hai. AI models har saal bade, data flow har saal multiple. Linear solution se exponential demand nahi sambhalti — optical jump zaroori hai.
- 3. Power/heat = data centre ka sabse bada kharcha. Optical interconnect power efficient hai. Jab bijli ka bill arabon me ho, efficiency directly profit hai — hyperscalers isme invest karenge hi.
- 4. Co-packaged optics roadmap on hai. Industry leaders (incl. NVIDIA direction) optical ko package ke andar laa rahe hain — supply chain ko follow karna majboori hai.
- 5. Picks-and-shovels durability. GPU war me chahe koi bhi jeete, optical plumbing sabko chahiye. Diversified, structural demand.
- 6. High barrier to entry. Photonics manufacturing, packaging, IP — ye raaton-raat copy nahi hota. Jo leaders hain, unka moat strong hai.
- 7. Hyperscaler capex record pe. Cloud giants AI infra pe historic amounts laga rahe hain — aur interconnect us capex ka growing hissa hai.
- 8. Under-owned / under-covered. Retail ka dhyaan GPUs pe, optical layer pe spotlight kam. Kam attention = kam premium = early entry ka mauka (mera contrarian point).
History Rhymes — Aisा Pehle Bhi Hua Hai
Mera confidence sirf aaj ki hype se nahi — pattern se aata hai:
- 1999–2000 ka fibre boom: Internet aaya to "optical networking" stocks rocket hue (phir bubble bhi fata — yeh sabak bhi yaad rakhna). Lekin lesson: jab connectivity bottleneck banta hai, optical ki taraf paisa daudta hai.
- 2016–2018 cloud transceiver cycle: Data-centre buildout me optical transceiver companies ne strong multi-year run diya, kyunki cloud ko bandwidth chahiye tha.
- 2023–2025 AI/GPU wave: Pehle GPUs chale (NVIDIA), phir memory (HBM), phir networking. Har wave me spotlight "next layer" pe shift hota gaya. Mera maanna: optical/photonics next logical layer hai jise abhi tak full credit nahi mila.
Pattern same hai: bottleneck → demand → leaders ko multi-year tailwind. Aur har baar, jo log layer ke "ek step aage" dekh paaye, unhe best risk-reward mila.
Main Galat Kahan Ho Sakta Hoon (Invalidation)
Honest thesis me ye section sabse zaroori hai:
- AI capex slowdown — agar hyperscalers spending kam karein (recession/over-build), to poora optical demand cycle slip kar jaata hai.
- Copper/alternative tech unexpected jump — agar copper ya koi sasti alternative tech aur aage chali, to optical adoption dheemi ho sakti hai.
- Timeline lamba khinch jaaye — co-packaged optics mainstream hone me agar 1–2 ki jagah 3–4 saal lagein, to "1–2 year multibagger" wala part galat ho jaata hai (thesis sahi, timing galat).
- Valuation already rich — kuch leaders pehle hi run kar chuke ho sakte hain; high valuation pe entry karne pe achha business bhi bura trade ban sakta hai.
- Small-cap execution/dilution risk — Bucket 3 wale naam funding/execution pe fail ho sakte hain. Yahan multibagger ke saath wipeout ka risk barabar hai.
📋 Prediction Scorecard — 2027–2028 Me Tick Karenge
Yeh raha falsifiable part. Aaj 29 June 2026 hai. ~1–2 saal baad wapas aana aur tick karna:
Agar inme se zyadatar tick ho gaye — yaad rakhna, maine ye 29 June 2026 ko likha tha, jab sabki nazar sirf GPUs pe thi. Aur agar galat nikla — main isi page pe wapas aaunga aur likhunga ki kahan chuka.
Main Personally Kya Dekh Raha Hoon (Watchlist, Advice Nahi)
- Hyperscaler capex commentary — har quarter, cloud giants ka AI infra spending badh raha hai ya ruk raha hai.
- Co-packaged optics announcements — kaun production me la raha hai, kaun sirf roadmap dikha raha hai.
- Optical companies ki data-centre revenue mix — telecom se data-centre ki taraf shift kitna tez hai.
- Fabrinet jaise manufacturers ke order trends — picks-and-shovels ka leading indicator.
- India data-centre + fibre capex — STL/HFCL/Tejas ke order books aur margins.
- Valuations — kahीं leaders pehle se overheated to nahi. Achha business, galat price = bura trade.
Mera personal principle wahi hai jo har blog me hota hai: emergency fund (6 mahine) kabhi haath mat lagao, udhaar leke speculation kabhi mat karo, aur foreign/small-cap me position size chhoti rakho — chahe conviction kitni bhi strong ho. Thesis sahi ho ke bhi timing 1–2 saal aage-peeche ho sakti hai.
Ek Chhota Investor Isse Kaise Approach Kare (Practical Playbook)
Theory to theek hai, par "main, ek normal investor, isse kaise dekhu?" Yahan mera practical framework hai — phir bhi, ye advice nahi, sirf soch ka tareeka hai:
- Basket > single bet. Kisi ek "lottery ticket" stock pe sab mat lagao. Agar exposure lena hai to 3–5 names ka basket socho — kuch core leaders, kuch picks-and-shovels. Theme sahi ho sakti hai par individual stock galat — basket isi risk ko kam karta hai.
- Bucket-wise position sizing. Bucket 1 (core leaders) ko bada weight, Bucket 3 (speculative small-caps) ko bahut chhota — "kho gaya to bhi neend na ude" jitna. Speculative naam me galti karne ki gunjaish kam hoti hai.
- Staggered entry, lump-sum nahi. Ek hi din me sab mat khareedo. 4–6 mahine me thoda-thoda — kyunki ye sector volatile hai, aur ek news pe 20–30% jhatka normal hai.
- ETF/fund route bhi ek option. Agar individual stocks ka research/risk nahi lena, to semiconductor/AI-infrastructure thematic funds ya ETFs ke through indirect exposure le sakte ho — kam concentrated, kam stress.
- Valuation check. Achha business + galat (overheated) price = bura trade. Agar koi leader pehle hi 2–3x daud chuka hai, to entry pe extra savdhaan raho ya pullback ka wait karo.
- Time horizon clear rakho. Ye 1–2 (ya zyada) saal ka structural theme hai, intraday trade nahi. Agar 3 mahine me 2x chahiye to ye blog tumhare liye nahi hai.
- Foreign-stock basics samjho. US stocks ke liye LRS limit, currency risk, aur taxation (foreign assets disclosure) samajh lo. Capital gains pe planning ke liye neeche tools diye hain.
Sabse important: conviction aur recklessness me farak hota hai. Strong thesis ka matlab "all-in" nahi hota — matlab "sahi size me, sahi horizon ke saath, aankhein khuli rakh ke" hota hai.
Bottom Line
Aaj 29 June 2026 ko, jab duniya sirf GPU ka naam le rahi hai, mera nazariya ek layer aage hai: asli, structural, under-the-radar opportunity silicon photonics aur optical interconnect me hai. Jab tak data centre ban rahe hain, light-based data movement ki demand sirf badhegi. Iska direct exposure US optical leaders (Coherent, Lumentum, Marvell, Broadcom), picks-and-shovels (Fabrinet, Cisco, NVIDIA demand, GlobalFoundries) aur high-risk small-caps (POET, Credo, AAOI) me hai — aur India ka adjacent play fibre + networking (Sterlite, HFCL, Tejas) me hai.
Main ek hi cheez ka dawa karta hoon — main future me sochta hoon, aaj ke shor me nahi. Yeh thesis ab record pe hai, date ke saath, logic ke saath, aur galat hone ki shart ke saath. 1–2 saal baad milte hain, scorecard tick karne. 🔦

My call, in one breath: Everyone's eyes are on GPUs (NVIDIA). But the real bottleneck now is moving data inside the chip and from chip to chip — and copper has hit its limit. The solution is silicon photonics: sending data with light (photons) instead of copper, right on the silicon chip. When every big data centre is being built for AI, this tech isn't "optional" — it's becoming compulsory.
My bet: over the next 1–2 years, silicon photonics + optical interconnect will see a "quiet boom," and a few fundamentally strong US and Indian companies leading it could become multibaggers. This page is the timestamp of that thesis. Nobody will tell you straight — but the action is cooking right here.
I'm not a SEBI/SEC-registered advisor. I'm a founder who obsessively tracks technology trends and market behaviour. This blog isn't "tips" — it's my research-backed view, public and dated. Just like I wrote my gold-silver-crypto prediction, this one too is going on record.
And I'll write this clearly too: all of this is a high-risk zone with foreign + small-cap exposure. Read it fully first, understand it, then do your own research. Let's deep-dive.
First — What Is Silicon Photonics? (In Plain Language)
Inside your laptop, phone, and data centre, data travels through electrons (copper wires). The problem: as data gets larger and faster, copper starts heating up, the signal degrades, and power consumption skyrockets. Past a certain limit, copper can't go further — engineers call this the "copper wall."
The idea of silicon photonics is simple: instead of electrons, use light (photons) to send data — and do it right on top of the silicon chip, within the regular chip-manufacturing process. The benefits of sending data with light:
- Much higher speed/bandwidth — light can carry many times more data at once.
- Less power + less heat — over distance, photons are far more efficient than electrons.
- No distance problem — copper weakens within a few cm; light travels meters/kilometres easily.
We've seen fibre-optic cable in the internet for years (data via light, over long distances). Silicon photonics brings that tech inside the chip, at the micro level. That's why calling it the "future of fibre cable" isn't wrong — it brings fibre's power right next to the processor.
Why This Boom, and Why NOW?
In one line: AI data centres. When GPT-like models train and run, thousands of GPUs have to talk to each other — massive amounts of data, super-fast, continuously. This "interconnect" (the layer joining the chips) has now become the biggest bottleneck. However powerful a GPU is, if data doesn't arrive on time it sits idle — and an idle GPU = burnt money.
That's why the industry is rapidly moving towards "co-packaged optics" (CPO) — placing the optical engine right inside the switch/GPU package, so data moves via light, not copper. NVIDIA itself has announced a silicon photonics / co-packaged optics direction for its future networking switches. When the industry's biggest player heads in this direction, the entire supply chain has to follow.
My point: as long as data centres are being built (and this is only the beginning), demand for silicon photonics + optical interconnect is going to rise the most. It has gone from "nice to have" to "must have." And when demand is structural, the leading companies are riding a multi-year tailwind.
Why Nobody Is Telling You Straight (The "Khichdi")
This part is important. Silicon photonics isn't consumer-facing — there's no iPhone-like product you can see. It's B2B, infrastructure-layer tech hidden inside the data centre. The media's and retail's full attention is on GPUs (NVIDIA), because that's the "face." But the optical plumbing that feeds data to every GPU — there's very little spotlight on it.
This is exactly what happens in every big tech cycle: during a gold rush, the gold-seekers (GPUs) are in the headlines — but over the long race, those selling the "picks & shovels" (optical components, manufacturing) quietly make fortunes too. Silicon photonics is the new, under-the-radar version of that picks-and-shovels layer. By the time it becomes the "mainstream story," the early move will already be done.
A Simple Analogy — So the Picture Is Crystal Clear
Imagine a very large office building (= AI data centre) with thousands of people (= GPUs) working in it who constantly need to send each other messages. Until now those messages were sent by dropping a ball into a small tube (= electrons in copper). When there were fewer people, it was fine. But now millions of people have entered the building, and the tubes are heating up, jamming, and the AC bill (= power) is exploding.
Silicon photonics means — now send the message via a beam of light (laser), with an optical "pipe" right next to every desk. Light doesn't heat up, doesn't jam, and a single pipe can carry thousands of messages at once in different colours. This makes the building 10x more efficient. The company that builds these "light pipes" and their laser-engines is the silent supplier of the whole building boom. That's the entire thesis in one line: when the building (data centre) is being built, the light-pipe maker will never go hungry.
The US Leaders — Who Are Driving This Tech
Here I'm splitting companies into 3 buckets. This is NOT a buy/sell recommendation — it's just an educational map of "who is working in this space." Be sure to do your own research on every name.
🟦 Bucket 1: Core Optical Leaders
- Coherent (COHR) — a big player in lasers + optical components + datacom transceivers. A direct beneficiary of AI data-centre optics demand. Vertically integrated (from indium phosphide all the way to modules).
- Lumentum (LITE) — optical components & lasers; growing exposure in cloud/datacenter transceivers. A fairly pure-ish photonics play.
- Marvell (MRVL) — custom AI silicon + electro-optics & optical DSPs (via the Inphi acquisition). Central to the co-packaged optics roadmap. This is that rare "silicon + photonics both" combo.
- Broadcom (AVGO) — networking switches (Tomahawk/Jericho) + co-packaged optics initiatives. Mega-cap, but a direct gatekeeper of the optical interconnect shift.
🟩 Bucket 2: Picks & Shovels (The Most Underrated)
- Fabrinet (FN) — this is my favourite "behind the scenes" name. It's a contract manufacturer of optical modules — meaning many big companies (optical transceivers, photonics modules) get them built here. Whoever wins, the manufacturer gets the order. Classic picks-and-shovels.
- Cisco (CSCO) — has acquired Acacia (coherent optics) and Luxtera (silicon photonics). A sleeping giant that holds serious photonics IP.
- NVIDIA (NVDA) — not directly a photonics company, but the engine of demand. Their silicon-photonics / co-packaged-optics networking roadmap fuels the entire supply chain. Indirect, but foundational.
- GlobalFoundries (GFS) — a silicon photonics foundry (the factory that makes chips) with a dedicated photonics platform. Exposure to the "factory layer."
🟥 Bucket 3: High-Risk, High-Reward Small/Mid Caps
⚠️ This is the most speculative bucket — here a multibagger is possible, but it can also go to zero. Only money you can afford to lose.
- POET Technologies (POET) — a pure-play small-cap in optical interposers. If their tech catches mainstream adoption, the leverage is big; but the execution & funding risk is just as big.
- Credo Technology (CRDO) — high-speed connectivity (active electrical/optical cables). An adjacent play on the interconnect bottleneck.
- Applied Optoelectronics (AAOI) — datacenter optical transceivers; highly volatile, but leveraged to the data-centre optics cycle.
The India Angle — The Honest Picture
Here I'll be absolutely straight, because this is where people make mistakes. There's no big pure silicon-photonics chip public company in India right now — this chip-level tech is mostly held by the US/Taiwan. But that doesn't mean there's nothing for an Indian investor. India's real leverage is in optical fibre + networking + data-centre infrastructure — which rides the same AI/data wave:
- Sterlite Technologies (STL) — India's largest optical fibre & cable company. Data explosion = fibre demand. It doesn't make silicon photonics chips, but it's the backbone supplier of the "light-based data" ecosystem.
- HFCL Ltd — optical fibre cable + telecom & networking equipment. India's play on 5G + fibre + data-centre connectivity.
- Tejas Networks (Tata Group) — optical & data networking equipment. With Tata's semiconductor + networking ambitions, this is a strategic long-term name.
And one more layer — data centre buildout in India. As hyperscale data centres get built in India, demand for fibre, networking gear, and (eventually) advanced optics will rise structurally. Plus, India's semiconductor mission could bring in photonics packaging down the line. My view: India's 1–2 year direct play isn't the silicon photonics chip, but the fibre + networking infra around it. That's why I keep them in a separate bucket — same wave, different risk profile.
8 Criteria — Why There's Substance in This Thesis
A thesis is only serious when there are structural reasons behind it. Here are my 8 angles:
- 1. The copper wall is real. It's a physics limit — at high speed copper gets hot, weak, power-hungry. Optical is the direct answer. This isn't fashion, it's engineering necessity.
- 2. Bandwidth demand is exponential. AI models get bigger every year, data flow multiplies every year. A linear solution can't handle exponential demand — the optical jump is essential.
- 3. Power/heat = a data centre's biggest cost. Optical interconnect is power-efficient. When the electricity bill is in the billions, efficiency is directly profit — hyperscalers will invest in it regardless.
- 4. The co-packaged optics roadmap is on. Industry leaders (incl. NVIDIA's direction) are bringing optical inside the package — the supply chain is compelled to follow.
- 5. Picks-and-shovels durability. Whoever wins the GPU war, everyone needs the optical plumbing. Diversified, structural demand.
- 6. High barrier to entry. Photonics manufacturing, packaging, IP — this isn't copied overnight. The leaders that exist have a strong moat.
- 7. Hyperscaler capex at record highs. Cloud giants are spending historic amounts on AI infra — and interconnect is a growing share of that capex.
- 8. Under-owned / under-covered. Retail's attention is on GPUs, the optical layer gets little spotlight. Less attention = less premium = a chance for early entry (my contrarian point).
History Rhymes — This Has Happened Before
My confidence comes not just from today's hype — it comes from the pattern:
- The 1999–2000 fibre boom: when the internet arrived, "optical networking" stocks rocketed (then the bubble also burst — remember that lesson too). But the lesson: when connectivity becomes the bottleneck, money runs towards optical.
- The 2016–2018 cloud transceiver cycle: in the data-centre buildout, optical transceiver companies delivered a strong multi-year run, because the cloud needed bandwidth.
- The 2023–2025 AI/GPU wave: first GPUs ran (NVIDIA), then memory (HBM), then networking. In each wave the spotlight shifted to the "next layer." My view: optical/photonics is the next logical layer that hasn't yet got full credit.
The pattern is the same: bottleneck → demand → a multi-year tailwind for the leaders. And every time, those who saw "one step ahead" of the layer got the best risk-reward.
Where I Could Be Wrong (Invalidation)
This section is the most essential part of an honest thesis:
- AI capex slowdown — if hyperscalers cut spending (recession/over-build), the entire optical demand cycle slips.
- Unexpected jump in copper/alternative tech — if copper or some cheaper alternative tech advances further, optical adoption could slow.
- The timeline drags on — if co-packaged optics takes 3–4 years to go mainstream instead of 1–2, the "1–2 year multibagger" part turns out wrong (thesis right, timing wrong).
- Valuation already rich — some leaders may have already run; entering at a high valuation can turn even a good business into a bad trade.
- Small-cap execution/dilution risk — the Bucket 3 names can fail on funding/execution. Here the multibagger comes with an equal risk of wipeout.
📋 Prediction Scorecard — To Tick in 2027–2028
Here's the falsifiable part. Today is 29 June 2026. Come back in ~1–2 years and tick these:
If most of these tick off — remember, I wrote this on 29 June 2026, when everyone's eyes were on GPUs alone. And if I'm wrong — I'll come back to this very page and write where I missed.
What I'm Personally Watching (Watchlist, Not Advice)
- Hyperscaler capex commentary — every quarter, whether the cloud giants' AI infra spending is rising or stalling.
- Co-packaged optics announcements — who is bringing it into production, who is only showing a roadmap.
- Optical companies' data-centre revenue mix — how fast the shift from telecom to data-centre is.
- Order trends of manufacturers like Fabrinet — a leading indicator for picks-and-shovels.
- India data-centre + fibre capex — the order books and margins of STL/HFCL/Tejas.
- Valuations — whether the leaders are already overheated. A good business at the wrong price = a bad trade.
My personal principle is the same as in every blog: never touch your emergency fund (6 months), never speculate with borrowed money, and keep your position size small in foreign/small-caps — no matter how strong the conviction. Even if the thesis is right, the timing can be off by 1–2 years.
How a Small Investor Should Approach This (Practical Playbook)
The theory is fine, but "how do I, a normal investor, look at this?" Here's my practical framework — still, this isn't advice, just a way of thinking:
- Basket > single bet. Don't put everything on one "lottery ticket" stock. If you want exposure, think of a basket of 3–5 names — some core leaders, some picks-and-shovels. The theme can be right but an individual stock wrong — a basket reduces exactly this risk.
- Bucket-wise position sizing. Give Bucket 1 (core leaders) a bigger weight, and Bucket 3 (speculative small-caps) a very small one — only as much as "won't cost you sleep if it's gone." Speculative names leave little room for mistakes.
- Staggered entry, not lump-sum. Don't buy it all in one day. Spread it over 4–6 months — because this sector is volatile, and a 20–30% jolt on a single news item is normal.
- The ETF/fund route is also an option. If you don't want the research/risk of individual stocks, you can take indirect exposure through semiconductor/AI-infrastructure thematic funds or ETFs — less concentrated, less stress.
- Valuation check. A good business + the wrong (overheated) price = a bad trade. If a leader has already run 2–3x, be extra cautious on entry or wait for a pullback.
- Keep the time horizon clear. This is a 1–2 (or more) year structural theme, not an intraday trade. If you want a 2x in 3 months, this blog isn't for you.
- Understand foreign-stock basics. For US stocks, understand the LRS limit, currency risk, and taxation (foreign assets disclosure). For planning capital gains, the tools are linked below.
Most important: there's a difference between conviction and recklessness. A strong thesis doesn't mean "all-in" — it means "in the right size, with the right horizon, eyes wide open."
Bottom Line
Today, on 29 June 2026, when the world is only chanting GPU, my view is one layer ahead: the real, structural, under-the-radar opportunity is in silicon photonics and optical interconnect. As long as data centres are being built, demand for light-based data movement will only grow. Its direct exposure is in US optical leaders (Coherent, Lumentum, Marvell, Broadcom), picks-and-shovels (Fabrinet, Cisco, NVIDIA demand, GlobalFoundries) and high-risk small-caps (POET, Credo, AAOI) — and India's adjacent play is in fibre + networking (Sterlite, HFCL, Tejas).
I claim only one thing — I think about the future, not the noise of today. This thesis is now on record, with a date, with logic, and with the condition for being wrong. See you in 1–2 years, to tick the scorecard. 🔦

मेरी बात, एक साँस में: सबकी नज़र GPUs (NVIDIA) पर है। लेकिन असली bottleneck अब chip के अंदर और chip-to-chip data move करना है — और copper अपनी limit पर पहुँच चुका है। इसका solution है silicon photonics: copper की जगह light (photons) से data भेजना, सीधे silicon chip पर। जब हर बड़ा data centre AI के लिए बन रहा है, तो ये tech "optional" नहीं — compulsory बन रही है।
मेरा दाँव: अगले 1–2 साल में silicon photonics + optical interconnect का एक "quiet boom" आएगा, और इसमें lead कर रही कुछ fundamentally strong US और Indian companies multibagger बन सकती हैं। यह page उस thesis का timestamp है। कोई तुम्हें सीधे नहीं बताएगा — पर खिचड़ी यहीं पक रही है।
मैं कोई SEBI/SEC-registered advisor नहीं हूँ। मैं एक founder हूँ जो technology trends और market behaviour को obsessively track करता है। ये blog "tips" नहीं — ये मेरा research-backed नज़रिया है, public और dated। जैसे मैंने gold-silver-crypto वाली prediction लिखी थी, वैसे ही यह भी record पर जा रहा है।
और मैं ये भी साफ़ लिख देता हूँ: ये सब foreign + small-cap exposure वाला high-risk zone है। पहले पूरा पढ़ो, समझो, फिर अपना research करो। चलो deep dive करते हैं।
पहले — Silicon Photonics है क्या? (आसान भाषा में)
आपके laptop, phone, data centre — सबके अंदर data electrons (copper wires) के ज़रिए travel करता है। Problem: जैसे-जैसे data बहुत ज़्यादा और बहुत fast होता है, copper गरम होने लगता है, signal ख़राब होने लगता है, और बिजली (power) बहुत ज़्यादा लगती है। एक limit के बाद copper आगे नहीं जा सकता — इसे engineers "copper wall" कहते हैं।
Silicon photonics का idea simple है: electrons की जगह light (photons) use करो data भेजने के लिए — वो भी सीधे silicon chip के ऊपर, regular chip manufacturing process में ही। Light से data भेजने के फ़ायदे:
- बहुत ज़्यादा speed/bandwidth — light से एक ही वक़्त में कई गुना ज़्यादा data।
- कम power + कम heat — long distance पर photons electrons से कहीं efficient।
- Distance का problem नहीं — copper कुछ cm में weak हो जाता है; light meters/kilometres आसानी से।
Fibre-optic cable तो हमने सालों से internet में देखा है (light से data, लंबी दूरी)। Silicon photonics उस tech को chip के अंदर, micro-level पर ले आता है। यही reason है कि इसे "future of fibre cable" कहना ग़लत नहीं — ये fibre की ताक़त को सीधे processor के पास ले जाता है।
ये Boom क्यों, और क्यों अभी?
एक line में: AI data centres. जब GPT-जैसे models train और run होते हैं, तो हज़ारों GPUs को आपस में बात करनी पड़ती है — massive amount of data, super-fast, लगातार। ये "interconnect" (chips को जोड़ने वाला layer) अब सबसे बड़ा bottleneck बन गया है। GPU कितना भी powerful हो, अगर data time पर नहीं पहुँचा तो वो idle बैठता है — और idle GPU = जला हुआ पैसा।
इसीलिए industry तेज़ी से "co-packaged optics" (CPO) की तरफ़ बढ़ रही है — यानी optical engine को सीधे switch/GPU package के अंदर बिठा देना, ताकि data light से move हो, copper से नहीं। NVIDIA ने ख़ुद अपने future networking switches में silicon photonics / co-packaged optics का direction announce किया है। जब industry का सबसे बड़ा player इस direction में जाता है, तो पूरी supply chain को follow करना पड़ता है।
मेरा point: जब तक data centre बन रहे हैं (और ये तो अभी शुरुआत है), silicon photonics + optical interconnect की demand सबसे ज़्यादा बढ़ने वाली है। ये "nice to have" से "must have" बन चुकी है। और जब demand structural होती है, तब leading companies multi-year tailwind पर होती हैं।
क्यों कोई सीधा नहीं बता रहा (The "Khichdi")
ये part important है। Silicon photonics consumer-facing नहीं है — कोई iPhone जैसा product नहीं जो आपको दिखे। ये B2B, infrastructure-layer tech है जो data centre के अंदर छुपी होती है। Media और retail का पूरा ध्यान GPUs (NVIDIA) पर है, क्योंकि वो "face" है। लेकिन हर GPU को data feed करने वाली optical plumbing — उस पर spotlight बहुत कम है।
यही होता है हर बड़े tech cycle में: जब gold rush चलता है, तो सोना ढूँढने वाले (GPUs) headlines में होते हैं — पर लंबी race में "picks & shovels" बेचने वाले (optical components, manufacturing) भी quietly fortune बनाते हैं। Silicon photonics उस picks-and-shovels layer का नया, under-the-radar version है। जब तक ये "mainstream story" बनेगी, तब तक शुरुआती move हो चुका होगा।
एक आसान Analogy — ताकि picture clear हो जाए
सोचो एक बहुत बड़ी office building है (= AI data centre), जिसमें हज़ारों लोग (= GPUs) काम कर रहे हैं और उन्हें एक दूसरे तक constant messages भेजनी हैं। अभी तक ये messages छोटे tube में ball डाल के (= electrons in copper) भेजी जा रही थीं। जब लोग कम थे, ठीक था। पर अब building में लाखों लोग आ गए, और tube गरम हो रहे हैं, जाम हो रहे हैं, और AC का bill (= power) फट रहा है।
Silicon photonics का मतलब है — अब message रोशनी की किरण (laser) से भेजो, सीधे हर desk के पास optical "pipe" लगा के। Light गरम नहीं होती, जाम नहीं होती, और एक ही pipe में एक साथ हज़ारों messages अलग-अलग colours में जा सकती हैं। इससे building 10x ज़्यादा efficient हो जाती है। जो company ये "light pipes" और उनके laser-engines बनाती है — वो इस पूरी building boom की silent supplier है। बस यही है पूरा thesis, एक line में: जब building (data centre) बन रही हो, light-pipe बनाने वाला कभी भूखा नहीं रहेगा।
The US Leaders — जो इस tech को drive कर रहे हैं
यहाँ मैं companies को 3 buckets में बाँट रहा हूँ। ये buy/sell recommendation नहीं है — ये सिर्फ़ "कौन इस space में काम कर रहा है" का educational map है। हर नाम के साथ अपना research ज़रूर करना।
🟦 Bucket 1: Core Optical Leaders
- Coherent (COHR) — lasers + optical components + datacom transceivers का बड़ा player। AI data-centre optics demand का सीधा beneficiary। Vertically integrated (indium phosphide से ले के modules तक)।
- Lumentum (LITE) — optical components & lasers; cloud/datacenter transceivers में growing exposure। Photonics का pure-ish play।
- Marvell (MRVL) — custom AI silicon + electro-optics & optical DSPs (Inphi acquisition के ज़रिए)। Co-packaged optics roadmap में central। ये "silicon + photonics दोनों" वाला rare combo है।
- Broadcom (AVGO) — networking switches (Tomahawk/Jericho) + co-packaged optics initiatives। Mega-cap, पर optical interconnect shift का direct gatekeeper।
🟩 Bucket 2: Picks & Shovels (सबसे Underrated)
- Fabrinet (FN) — ये मेरा favourite "behind the scenes" नाम है। ये optical modules का contract manufacturer है — मतलब कई बड़ी companies (optical transceivers, photonics modules) इनसे बनवाती हैं। जो भी जीते, manufacturer को order मिलता है। Classic picks-and-shovels।
- Cisco (CSCO) — Acacia (coherent optics) और Luxtera (silicon photonics) को acquire कर चुका है। एक sleeping giant जिसके पास serious photonics IP है।
- NVIDIA (NVDA) — directly photonics company नहीं, पर demand का engine। इनके silicon-photonics / co-packaged-optics networking roadmap से पूरी supply chain को fuel मिलता है। Indirect, पर foundational।
- GlobalFoundries (GFS) — silicon photonics foundry (chip बनाने वाली factory) जिसके पास dedicated photonics platform है। "Factory layer" का exposure।
🟥 Bucket 3: High-Risk, High-Reward Small/Mid Caps
⚠️ ये सबसे speculative bucket है — यहाँ multibagger बन सकता है, पर zero भी हो सकता है। सिर्फ़ वो पैसा जो आप खो सकते हो।
- POET Technologies (POET) — optical interposer का pure-play small-cap। अगर इनकी tech mainstream adoption पकड़ ले, तो leverage बड़ा है; पर execution & funding risk भी उतना ही।
- Credo Technology (CRDO) — high-speed connectivity (active electrical/optical cables)। Interconnect bottleneck का adjacent play।
- Applied Optoelectronics (AAOI) — datacenter optical transceivers; highly volatile, but data-centre optics cycle में leveraged।
The India Angle — Honest Picture
यहाँ मैं बिल्कुल सीधी बात करूँगा, क्योंकि यहीं लोग ग़लती करते हैं। India में अभी कोई बड़ी pure silicon-photonics chip वाली public company नहीं है — ये chip-level tech mostly US/Taiwan के पास है। लेकिन इसका मतलब ये नहीं कि Indian investor के लिए कुछ नहीं। India का असली leverage optical fibre + networking + data-centre infrastructure में है — जो इसी AI/data wave पर ride करता है:
- Sterlite Technologies (STL) — India की सबसे बड़ी optical fibre & cable company। Data explosion = fibre demand। Silicon photonics chip नहीं बनाती, पर "light-based data" ecosystem की backbone supplier है।
- HFCL Ltd — optical fibre cable + telecom & networking equipment। 5G + fibre + data-centre connectivity का India play।
- Tejas Networks (Tata Group) — optical & data networking equipment। Tata के semiconductor + networking ambitions के साथ ये एक strategic long-term नाम है।
और एक और layer — data centre buildout in India। जैसे-जैसे India में hyperscale data centres बन रहे हैं, fibre, networking gear, और (eventually) advanced optics की demand structurally बढ़ेगी। Plus, India के semiconductor mission में आगे चल के photonics packaging भी आ सकता है। मेरा मानना: India का 1–2 साल का direct play silicon photonics chip नहीं, बल्कि उसके आस-पास का fibre + networking infra है। इसीलिए मैं इन्हें अलग bucket में रखता हूँ — same wave, अलग risk profile।
8 Criteria — जिनकी वजह से इस thesis में दम है
एक thesis तभी serious है जब उसके पीछे structural reasons हों। यहाँ मेरे 8 angles:
- 1. Copper wall real है। Physics की limit है — high speed पर copper गरम, weak, power-hungry हो जाता है। Optical इसका सीधा जवाब है। ये fashion नहीं, engineering necessity है।
- 2. Bandwidth demand exponential है। AI models हर साल बड़े, data flow हर साल multiple। Linear solution से exponential demand नहीं सँभलती — optical jump ज़रूरी है।
- 3. Power/heat = data centre का सबसे बड़ा खर्चा। Optical interconnect power efficient है। जब बिजली का bill अरबों में हो, efficiency directly profit है — hyperscalers इसमें invest करेंगे ही।
- 4. Co-packaged optics roadmap on है। Industry leaders (incl. NVIDIA direction) optical को package के अंदर ला रहे हैं — supply chain को follow करना मजबूरी है।
- 5. Picks-and-shovels durability. GPU war में चाहे कोई भी जीते, optical plumbing सबको चाहिए। Diversified, structural demand।
- 6. High barrier to entry. Photonics manufacturing, packaging, IP — ये रातों-रात copy नहीं होता। जो leaders हैं, उनका moat strong है।
- 7. Hyperscaler capex record पर। Cloud giants AI infra पर historic amounts लगा रहे हैं — और interconnect उस capex का growing हिस्सा है।
- 8. Under-owned / under-covered. Retail का ध्यान GPUs पर, optical layer पर spotlight कम। कम attention = कम premium = early entry का मौक़ा (मेरा contrarian point)।
History Rhymes — ऐसा पहले भी हुआ है
मेरा confidence सिर्फ़ आज की hype से नहीं — pattern से आता है:
- 1999–2000 का fibre boom: Internet आया तो "optical networking" stocks rocket हुए (फिर bubble भी फटा — यह सबक भी याद रखना)। लेकिन lesson: जब connectivity bottleneck बनता है, optical की तरफ़ पैसा दौड़ता है।
- 2016–2018 cloud transceiver cycle: Data-centre buildout में optical transceiver companies ने strong multi-year run दिया, क्योंकि cloud को bandwidth चाहिए था।
- 2023–2025 AI/GPU wave: पहले GPUs चले (NVIDIA), फिर memory (HBM), फिर networking। हर wave में spotlight "next layer" पर shift होता गया। मेरा मानना: optical/photonics next logical layer है जिसे अभी तक full credit नहीं मिला।
Pattern same है: bottleneck → demand → leaders को multi-year tailwind. और हर बार, जो लोग layer के "एक step आगे" देख पाए, उन्हें best risk-reward मिला।
मैं ग़लत कहाँ हो सकता हूँ (Invalidation)
Honest thesis में ये section सबसे ज़रूरी है:
- AI capex slowdown — अगर hyperscalers spending कम करें (recession/over-build), तो पूरा optical demand cycle slip कर जाता है।
- Copper/alternative tech unexpected jump — अगर copper या कोई सस्ती alternative tech और आगे चली, तो optical adoption धीमी हो सकती है।
- Timeline लंबा खिंच जाए — co-packaged optics mainstream होने में अगर 1–2 की जगह 3–4 साल लगें, तो "1–2 year multibagger" वाला part ग़लत हो जाता है (thesis सही, timing ग़लत)।
- Valuation already rich — कुछ leaders पहले ही run कर चुके हो सकते हैं; high valuation पर entry करने पर अच्छा business भी बुरा trade बन सकता है।
- Small-cap execution/dilution risk — Bucket 3 वाले नाम funding/execution पर fail हो सकते हैं। यहाँ multibagger के साथ wipeout का risk बराबर है।
📋 Prediction Scorecard — 2027–2028 में Tick करेंगे
यह रहा falsifiable part। आज 29 June 2026 है। ~1–2 साल बाद वापस आना और tick करना:
अगर इनमें से ज़्यादातर tick हो गए — याद रखना, मैंने ये 29 June 2026 को लिखा था, जब सबकी नज़र सिर्फ़ GPUs पर थी। और अगर ग़लत निकला — मैं इसी page पर वापस आऊँगा और लिखूँगा कि कहाँ चूका।
मैं Personally क्या देख रहा हूँ (Watchlist, Advice नहीं)
- Hyperscaler capex commentary — हर quarter, cloud giants का AI infra spending बढ़ रहा है या रुक रहा है।
- Co-packaged optics announcements — कौन production में ला रहा है, कौन सिर्फ़ roadmap दिखा रहा है।
- Optical companies की data-centre revenue mix — telecom से data-centre की तरफ़ shift कितना तेज़ है।
- Fabrinet जैसे manufacturers के order trends — picks-and-shovels का leading indicator।
- India data-centre + fibre capex — STL/HFCL/Tejas के order books और margins।
- Valuations — कहीं leaders पहले से overheated तो नहीं। अच्छा business, ग़लत price = बुरा trade।
मेरा personal principle वही है जो हर blog में होता है: emergency fund (6 महीने) कभी हाथ मत लगाओ, उधार लेके speculation कभी मत करो, और foreign/small-cap में position size छोटी रखो — चाहे conviction कितनी भी strong हो। Thesis सही हो के भी timing 1–2 साल आगे-पीछे हो सकती है।
एक छोटा Investor इसे कैसे approach करे (Practical Playbook)
Theory तो ठीक है, पर "मैं, एक normal investor, इसे कैसे देखूँ?" यहाँ मेरा practical framework है — फिर भी, ये advice नहीं, सिर्फ़ सोच का तरीक़ा है:
- Basket > single bet. किसी एक "lottery ticket" stock पर सब मत लगाओ। अगर exposure लेना है तो 3–5 names का basket सोचो — कुछ core leaders, कुछ picks-and-shovels। Theme सही हो सकती है पर individual stock ग़लत — basket इसी risk को कम करता है।
- Bucket-wise position sizing. Bucket 1 (core leaders) को बड़ा weight, Bucket 3 (speculative small-caps) को बहुत छोटा — "खो गया तो भी नींद न उड़े" जितना। Speculative नाम में ग़लती करने की गुंजाइश कम होती है।
- Staggered entry, lump-sum नहीं। एक ही दिन में सब मत ख़रीदो। 4–6 महीने में थोड़ा-थोड़ा — क्योंकि ये sector volatile है, और एक news पर 20–30% झटका normal है।
- ETF/fund route भी एक option. अगर individual stocks का research/risk नहीं लेना, तो semiconductor/AI-infrastructure thematic funds या ETFs के ज़रिए indirect exposure ले सकते हो — कम concentrated, कम stress।
- Valuation check. अच्छा business + ग़लत (overheated) price = बुरा trade। अगर कोई leader पहले ही 2–3x दौड़ चुका है, तो entry पर extra सावधान रहो या pullback का wait करो।
- Time horizon clear रखो। ये 1–2 (या ज़्यादा) साल का structural theme है, intraday trade नहीं। अगर 3 महीने में 2x चाहिए तो ये blog तुम्हारे लिए नहीं है।
- Foreign-stock basics समझो। US stocks के लिए LRS limit, currency risk, और taxation (foreign assets disclosure) समझ लो। Capital gains पर planning के लिए नीचे tools दिए हैं।
सबसे important: conviction और recklessness में फ़र्क़ होता है। Strong thesis का मतलब "all-in" नहीं होता — मतलब "सही size में, सही horizon के साथ, आँखें खुली रख के" होता है।
Bottom Line
आज 29 June 2026 को, जब दुनिया सिर्फ़ GPU का नाम ले रही है, मेरा नज़रिया एक layer आगे है: असली, structural, under-the-radar opportunity silicon photonics और optical interconnect में है। जब तक data centre बन रहे हैं, light-based data movement की demand सिर्फ़ बढ़ेगी। इसका direct exposure US optical leaders (Coherent, Lumentum, Marvell, Broadcom), picks-and-shovels (Fabrinet, Cisco, NVIDIA demand, GlobalFoundries) और high-risk small-caps (POET, Credo, AAOI) में है — और India का adjacent play fibre + networking (Sterlite, HFCL, Tejas) में है।
मैं एक ही चीज़ का दावा करता हूँ — मैं future में सोचता हूँ, आज के शोर में नहीं। यह thesis अब record पर है, date के साथ, logic के साथ, और ग़लत होने की शर्त के साथ। 1–2 साल बाद मिलते हैं, scorecard tick करने। 🔦
