### @photonics-map — Estimate — structural map from curated research plus company filings
The AI datacenter's optical plumbing splits into two architectures — front-panel pluggable modules (800G to 1.6T) and emerging co-packaged optics — on ten shared layers: lasers, modulators, optical DSP, fiber attach, optical circuit switches, photonic foundries, assembly/packaging/test, thermal/liquid cooling, upstream materials, and 224G electronics. The map's rule: architecture transitions re-weight value across layers, not eliminate them. Co-packaging shifts bottlenecks toward optical engines, external lasers, detachable fiber attach, package integration, and wafer-level photonic test.
