$Lumentum(LITE)$ surged 8% this week, is up +143% YTD. $COHERENT(COHR)$ added +19% this week and continues to build momentum.
J.P. Morgan just raised LITE's target from $565 → $950. COHR from $245 → $300. Both: Overweight.
Why optical is back in the spotlight this week?
JPM, Goldman, the OFC data: The AI infrastructure buildout is accelerating, not slowing. CPO and OCS are no longer 2028 stories — they're 2H 2026 revenue. The market is still pricing these companies like boring legacy optical hardware companies. That's the mispricing. Memory started repricing six months ago. Optical is repricing now.

Memory prices just confirmed the AI hardware supercycle is real. Samsung reported Q1 earnings that demolished estimates. DRAM pricing: +103% quarter-over-quarter. NAND: +87% QoQ. Goldman Sachs raised Samsung's target to ₩285,000. The memory upcycle isn't a thesis anymore — it's a line item.

The biggest optical components conference of the year (OFC) just ended. OFC is where every major player in photonics shows their roadmap. This year's message was unambiguous: the "future technology" conversations from previous years are now purchase orders. Customers are signing contracts. Capacity is being booked years out.
What is optical module? Why does this matter?
You know how highways get congested when too many cars try to use them at once?
Data centers have the same problem. Millions of AI calculations are happening every second — and all that data needs to travel between chips, between servers, and between buildings at insane speeds.
Optical modules are the solution. Light travels faster. It uses less power. It doesn't generate as much heat.
Every time you use ChatGPT, watch a Netflix recommendation, or ask an AI assistant anything — your request flows through optical modules, probably multiple times.
Optical modules are the highways of AI infrastructure. And right now, those highways are being rebuilt from scratch.
Two technologies you need to know
Analysts keep throwing around "CPO" and "OCS." Here's what they actually mean:
CPO (Co-Packaged Optics) Traditional optical modules sit separately from the chips they serve — connected by short copper wires. CPO moves the optical module directly next to the chip it's talking to. Less distance = less energy lost = faster = cheaper to run.
OCS (Optical Circuit Switching) Traditional data centers use electronic switches to route traffic. OCS replaces those with optical switches — routing data as light, not electrons. Faster reconfiguration, lower latency, lower power.
Lumentum alone is on track to do $400M annualized in OCS revenue by H2 2026 — accelerating to $1B+ annualized in 2027 — backed by a multi-year, multi-billion dollar contract with a single hyperscaler.
Would you add these two optical stocks in your watchlist?
J.P. Morgan's summary in one line: LITE is the higher upside, higher risk bet. COHR is the "buy the whole sector without picking the winning horse" play.
Questions
Q1: Which optical module name looks most interesting to you right now?
-
A. LITE — high conviction on the multi-year CPO/OCS story, willing to hold through volatility
-
B. COHR — broader exposure, more predictable, Nvidia LTA gives visibility
Q2: Are optical modules the next memory — a structural investment theme for the next 2-3 years?

That said, Coherent Corp. is a cleaner, more balanced play. Its broader exposure and better demand visibility make it more resilient if macro conditions turn volatile, while LITE remains the higher-beta, higher-upside bet.
Overall, I do think optical modules are becoming a structural theme for the next few years. Signals from Optical Fiber Communication Conference and memory pricing confirm that AI infrastructure demand is now fully translating into real deployment — and capital is just starting to rotate into this layer.

LITE is often viewed as pure play for the next phase of optical networking. It is the clear market leader in Optical Circuit Switching.
Lumentum's revenue grew 65% YoY in early 2026 & is projected to grow nearly 77% for the full year.
Coherent is the powerhouse of the industry, offering a massive vertically integrated manufacturing footprint.
COHR is more diversified with a large industrial laser segment that provides a cushion if AI specific demand ever plateaus.
COHR also trades at lower valuation that LITE.
I would choose COHR since I am looking for more durable long term returns. While LITE has a higher percentage growth, COHR's superior manufacturing scale of 6 inch wafers & huge backlog provide a more stable foundation.

Optical modules have indeed become a structural investment theme for the next 2-3 years, mirroring the "High Bandwidth Memory" (HBM) narrative. Just as HBM became the critical bottleneck for GPU performance, 1.6T optical transceivers are now the essential "interconnect" bottleneck for scaling AI clusters. The supply chain dynamics are shifting from cyclical to structural because the physical limits of copper require a permanent transition to light-based data movement. With leading laser capacity sold out through 2027 and major players like Nvidia making multi-billion dollar prepayments to secure supply, optics are no longer a commodity but a strategic asset in the AI arms race.
Lumentum (LITE) is currently more "interesting" from a strategic standpoint. While Coherent offers stability through its diversified industrial base and Nvidia's Long-Term Agreement (LTA), LITE represents a concentrated bet on the next architectural evolution. Its massive backlog in Optical Circuit Switching (OCS) and the recent multi-year win for Co-packaged Optics (CPO) position it as the primary beneficiary of the industry's shift away from traditional pluggable modules toward integrated networking. For an investor looking for the "structural winner" of the next phase of AI infrastructure, LITE's pure-play exposure to these high-margin, next-gen technologies offers higher upside potential despite the volatility.
