POET's deal with Lumilens is a $500M validation that could move it from lab tech to commercial scale. The supply and joint development agreement starts with a $50M order for optical engines and could scale to $500M over five years, with samples in late 2026 and volume production in 2027. Its optical interposer integrates electronics and photonics in one chip-scale package, beating power-hungry pluggables. 2026 should be the year of validation, 2027 the year of revenue. x.com 

POET Technologies is the upstream pick-and-shovel for Celestial AI's Photonic Fabric, which Marvell just acquired for about $5B. POET supplies the light source that powers it, and Marvell has the hyperscaler relationships with AWS, Google and Meta to deploy it at scale. Revenue is still early, but once Marvell integrates Celestial and ramps production orders, the market should recognize POET's value; Q3 or Q4 2026 could be the inflection, and patience is required. x.com 

POET Technologies' Lumilens deal looks weak because Lumilens lacks the cash to pay for its purchase orders and needs POET's stock to soar to cash out. Lumilens has nothing in an ultra-competitive optics sector with China. Claims of billions in orders are false; any Amazon order depends on executing several steps first, while Coherent sells about $5B of optics after 30+ years with access to fabs, lasers and ICs. x.com  x.com 

POET Technologies is shifting from R&D to execution. Q4 earnings showed 10x year-over-year revenue growth with $430 million in cash. A $5 million-plus production order for POET Infinity optical engines is confirmed, and the company targets more than 30,000 engine shipments in 2026, with the 800G ramp starting in Q3. x.com 

Rising 1.6T switching demand favors optical suppliers, though their execution risks vary. Bank of America says the market could grow ~101% annually through 2030. Marvell's leading DSPs and Lumentum's supply-short 200G EML lasers are lowest risk; Applied Optoelectronics' capacity expansion and Fabrinet's customer concentration make them medium risk. Aeluma remains pre-commercial, while Lightwave Logic's polymer modulators are a high-risk moonshot despite its TSM partnership. x.com 

POET Technologies is uninvestable because its management has lost the trust of the big players. In April its CFO leaked information that led to the cancellation of Celestial AI and Marvell contracts. Being early in interposers and packaging does not make it a co-packaged optics winner, as others will catch up. Its TFLN partner QCI trails Hyperlight and is stuck on a 6-inch line, with no 8-inch wafer demo yet to show it can scale. x.com  x.com 

Optics and photonics should be among AI's biggest winners as faster GPU networks need optical connections that suppliers cannot expand quickly enough. Lumentum says some components are sold out through early 2029; Sivers is investing $30M to target more than 100M lasers a year, with operations expected in Q4 2027. Potential US restrictions on Chinese transceivers could reshape supply in 2027. Applied Optoelectronics and Sivers are the favorites. x.com  x.com 

POET Technologies is still very early in its growth. Revenue grew 112% year over year with six straight quarters of sequential growth, and it is showcasing new laser light source technology for AI interconnects this week. It is one worth being patient with. x.com 

POET is now an unknown after Night Market Research's short report alleged its partnership story is dead, so stepping aside makes sense until management gives verifiable counter-evidence. Per the report, Celestial AI says POET hasn't come up internally since 2023, Foxconn executives stopped using it two years ago, Luxshare executives never heard of it and its Toronto HQ was empty. The optical interconnect bottleneck is real, but Lumentum and Coherent are the durable picks in the subsector. x.com  … Show more

POET's new Lumilens order could make it a pivotal niche bottleneck in AI infrastructure, with a wide moat. Lumilens placed a $50M initial order for POET's AI photonic optical engines, with a potential $500M over five years. If it truly works, it could be colossal, a Vertiv-like story developing in real time. The CEO, a former GlobalFoundries vice president with foundry-level manufacturing experience, could make POET central to the photonics industry. x.com  x.com  x.com  x.com
