CPO Lasers

Sivers is the bleeding-edge independent DFB/CW laser supplier for Co-Packaged Optics (CPO) — the next-generation photonic architecture being deployed by every major hyperscaler. While LITE and COHR are fully allocated to NVIDIA, Sivers has emerged as the Tier-1 laser source for AMD CPO (via GFS), Marvell Celestial, Jabil 1.6T LRO, Ayar, and likely Apple silicon photonics. At a ~$1.5B MC vs. LITE at $60B+, the valuation gap is extraordinary for what is essentially the same critical chokepoint in the laser supply chain. CHIPS Act funding and a pending NASDAQ listing unlock US institutional capital that fund mandates previously barred.

AAOI is the largest US-based 1.6T optical transceiver and laser fab by projected capacity. Called at $30, now $150+. Amazon has purchase agreements and warrants with AAOI, making them a direct beneficiary of hyperscaler 1.6T validation. If they execute on becoming the largest 1.6T capacity in the US, Serenity sees $30B+ valuation long term.

MSSCorps holds a functional monopoly over CPO inspection — specifically non-destructive infrared (IR) leakage detection for Co-Packaged Optics yields. The CEO explicitly stated 'the company's goal is to seize a 90 percent share of the CPO inspection market' (translated: 100%, they just can't say antitrust). Customers include TSM, NVDA, AAPL, AMAT, LRCX, ASML, INTC. They've aggressively used litigation (Enli Tech lawsuit) to lock out rivals. At ~$1.2-1.4B MC for what could become a $5-9B monopoly.

Marvell's Celestial CPO architecture positions them as the 'mini-Broadcom' of AI networking ASICs. MSFT Maia ASIC ramp H2 2026 + Google TPU development talks for 2028 provide multi-year revenue visibility. The Celestial acquisition was transformative. Post-POET NDA breach, MRVL is likely sourcing lasers directly from SIVE — actually improving Sivers' position.

POET packages SIVE lasers into optical interposers for Marvell Celestial — but Marvell cancelled purchase orders after POET CFO violated the NDA. Small positions held. The packaging layer is easier to vertically integrate away than laser IP, making POET the most likely to be designed out long-term. $420M cash provides downside buffer.

Shunsin is Foxconn's optical packaging and test arm — literally a free piggyback ride to NVDA's CPO supply chain. Foxconn was selected as NVDA's exclusive rack-scale supplier for Groq accelerators, vertically integrating networking including Shunsin's optical packaging. Valued at less than LWLG despite being a production-stage company, not an R&D project.

Win Semi is the compound semiconductor foundry handling Sivers' volume scaling for DFB laser production. Already in supply chains for AVBO, SpaceX, QCOM, Mediatek, MTSI, NXPI, AAPL. When every frontier photonics and space company uses Win Semi, they are the invisible shovel seller of the CPO supercycle.
