Co-packaged optics is the next architecture transition in AI infrastructure. We mapped the full supply chain — 10 layers, 50+ companies, every chokepoint — and scored each node by how much downstream value it gates.
The current cycle is pluggable optics — EML-based transceivers (electro-absorption modulated lasers) from AAOI, Lumentum, Coherent. The next cycle is co-packaged optics: CW DFB lasers (continuous-wave distributed feedback) integrated onto a silicon photonics platform, packaged directly onto the switch ASIC. NVIDIA confirmed CPO for its next-generation Feynman platform. Spectrum-6 SPX is already shipping with optical integration.
The alpha is in the rotation. The companies that dominate the CPO cycle aren't the same ones winning the pluggable cycle. Some overlap (Coherent, Broadcom). Many don't. A $231M Swedish laser die company and a $1B Canadian optical interposer startup may gate more downstream value than all the current transceiver leaders combined.
10 layers from raw substrates to end customers. Node color indicates bottleneck severity. Click any node for details. Connections highlight supply chain dependencies — follow the path from a $231M laser die company to a $3T hyperscaler.
Ranked by asymmetry ratio — how much downstream value a single company or material gates relative to its own market capitalization. The highest-asymmetry nodes represent the most extreme mismatch between a company's current valuation and the value chain it enables.
The same graph-based methodology that powers this CPO analysis already caught a photonics supply chain winner. Here's the full chain of evidence.
AXT Inc (AXTI) is an indium phosphide substrate supplier sitting at Layer 1 of the photonics supply chain. When our graph first flagged it, the company had a market cap under $1B — yet it supplied the foundational material for every 800G/1.6T optical transceiver in production.
The graph scored AXTI with high asymmetry: a sub-billion-dollar company gating hundreds of billions in downstream AI infrastructure value. InP substrates have no substitute at these wavelengths. Lead times had stretched significantly. China manufactures 100% of AXT's wafers, adding geopolitical risk premium.
Our convergence system detected multiple independent data points confirming the thesis: institutional accumulation visible in 13F filings, options flow activity, and the supply chain graph positioning all converging on the same conclusion.
Result: AXTI re-rated from $24.79 to $44.43 — a +79.2% return since our graph detection on February 12, 2026. AAOI, the vertically integrated transceiver maker one layer downstream, returned +94.8% over the same period.
| Ticker | Entry | Current | Return |
|---|---|---|---|
| AAOI | $44.46 | $86.63 | +94.8% |
| AXTI | $24.79 | $44.43 | +79.2% |
| KEYS | $238.02 | $287.92 | +21.0% |
| COHR | $211.00 | $245.95 | +16.6% |
| LITE | $562.74 | $651.61 | +15.8% |
| FN | $495.55 | $499.15 | +0.7% |
| FORM | $96.73 | $94.46 | -2.3% |
| GFS | $45.01 | $43.31 | -3.8% |
Our bottleneck prediction engine tracks materials through a 4-stage lifecycle: architecture lock (design decisions that create future demand) → cross-demand convergence (multiple sectors competing for the same material) → capacity gap (demand outrunning supply) → earnings language shift (companies signaling constraints). Here's what it sees in the photonics supply chain.
