Gooch & Housego is a great defense long that is not expensively valued on future technology, with thin-film lithium niobate as an extra lottery ticket. @MoodyWriter13 notes major co-packaged optics deployments use silicon photonics, making TFLN a likely 2028+ supplement at 1.6T or 3.2T; Gooch & Housego's chance to be a player there is small and uncertain. x.com 

ASML's EUV R&D is starting to pay off through operating leverage. Q3 R&D fell as a share of sales, though one quarter is not a trend. Higher units, IBM sales and EUV/DUV prices put 2028 estimates well above the 2030 guide and ahead of consensus; shares look cheap at €1,530. Assuming 30% prepayment, liabilities imply €42-45bn of orders in 2026's first nine months, subject to invoicing lags. The proposed MATCH Act could restrict China sales; 2029-30 demand is less certain than 2028. x.com  x.com  … Show more

Gooch & Housego is not currently an AI photonics investment, because thin-film lithium niobate plays no role in co-packaged optics today. All major CPO deployments use silicon photonics; TFLN only becomes relevant as a supplement at 1.6T or 3.2T, likely a 2028+ play, and whether G&H will be competitive remains to be seen. That pushes back on @PhotonBull's case for G&H as the best TFLN pick. It is a solid company with strong defense tailwinds, and AI relevance may come in late 2027 or 2028. x.com  … Show more

Applied Optoelectronics guided Q3 revenue sharply higher to $255M-$290M with non-GAAP net income of $10.1M-$24.0M, showing growth turning into profit. It is expanding its Pearland, Texas, campus for 800G and 1.6T modules, and management expects orders to outstrip capacity through mid-2027. Its US-based, diversified manufacturing positions it for shifts away from Chinese optical modules, and as 800G shipments more than doubled in Q2, non-GAAP gross margin reached 29.8%. x.com 

Lumentum is seeing very bullish demand signals across near-package optics, lasers and links between data centers. Management sees NPO expanding the optical TAM, with about six core customers and revenue of $50M–$100M in Q4 2026 rising above $100M in Q1 2027. Lasers remain undersupplied: EML orders run into 2027 at rising prices. Lumentum holds about 80% of pump lasers, which it aims to quadruple by early 2028 as AI clusters spread across sites, with contract visibility over three years. x.com  … Show more

Coherent now has credible exposure to almost every optical architecture hyperscalers are exploring, and its Nvidia deal materially de-risks that roadmap. Nvidia's nonexclusive pact adds a multibillion-dollar purchase commitment, a $2B equity investment and access to five CPO product families. First CPO/NPO revenue targeted for H2 2026 matches Nvidia's timing. Data center and communications are already 72% of revenue. Qualification, standards, concentration and margins remain unsettled. x.com 

Nvidia's Q1 FY27 results materially improve demand visibility across the optics, networking and photonics stack. Revenue hit $81.6B, up 85%, with networking at $14.8B, up 199%, and Nvidia named multi-year optics deals with Coherent, Corning and Lumentum plus a Marvell partnership on NVLink Fusion and silicon photonics. AI cloud, industrial and enterprise revenue grew 31% sequentially versus 12% for hyperscale, so the buildout is spreading. Vera Rubin ramps in Q3. x.com 

Soitec's photonics-SOI business is accelerating sharply, making the stock cheaper on a bull case that still needs to play out. Q1 FY27 revenue rose 23% organically to €113m, with photonics-SOI up about 100%; Q2 is guided up over 30% and FY27 photonics revenue should more than double. If photonics becomes supply-constrained, near-idealistic 40-42% EBITDA margins on €750m revenue imply about 11x FY28 EV/EBITDA, versus 13.3x on prior consensus. Below about 70, confidence would return. x.com 

Tower Semiconductor's silicon photonics ramp is running ahead of schedule, per Wedbush, pulling it into a better revenue and margin mix from AI datacenter optics. Q1 revenue beat, gross margin hit 26.8%, and about $290 million of prepayments back $1.3 billion of contracted 2027 SiPh revenue, which management calls a floor. Wedbush sees CPO share shift as a risk from 2028 at the earliest. It raised its target to $300 from $140 but stays Neutral, seeing the good news as increasingly priced in. … Show more

inTEST's Q1 dip is short-term noise, since the real revenue should arrive in the second half of 2026 as orders tied to silicon photonics and HBM testing flood in. Revenue rose 27.2% to $33.9 million, margins expanded 400bp to 45.5%, backlog grew 35.5% to $51.8 million, and 2026 guidance rose to $130-135 million. The stock fell because new orders dropped 15.2% sequentially to $31.8 million, but hitting guidance implies heavy H2 orders, with volume testing lagging 1.6T sampling by 3-6 months. … Show more
