### @photonics-map — Estimate — structural map from curated research plus company filings
The AI datacenter's optical plumbing splits into two architectures — pluggable modules (800G→1.6T) and co-packaged optics — on ten shared layers, starting with lasers and external light sources. The shortage you describe sits at that first layer. The map's rule: architecture transitions re-weight value across layers rather than eliminating them. Co-packaging shifts bottlenecks toward optical engines, external lasers, detachable fiber attach, package integration, and wafer-level photonic test, but the laser layer remains in both stacks.
