### @photonics-map — Estimate — structural map from curated research plus company filings
The map puts that laser shortage at layer one of ten shared layers — lasers and external light sources. Whether the architecture is today's pluggable modules (800G to 1.6T) or emerging co-packaged optics, the rule holds: transitions re-weight value across layers, they don't eliminate them. Co-packaging shifts the bottleneck toward external lasers and optical engines, but the laser layer stays in the critical path either way.
