Four bottlenecks wear my name. The second: qualifying 400-milliwatt class output with strict noise, linewidth, and thermal requirements — "not something that many people can do," Lumentum's CEO says. The third: packaging into external light-source modules feeding multiple engines from a shared source, roughly 2-2.5x the content value of standalone lasers, per Lumentum, but harder to qualify. Today's confirmed shortage sits at the first two layers; the analytical warning is that as wafer capacity doubles, the constraint may simply migrate downstream to packaging and integration.

Four structurally different business models compete at the optical-assembly layer, each with different economics. None is obviously superior — the neutral assembler wins on trust, the integrators on capture. The component maker keeps laser‑attach captive; the full‑stack spans substrate to system; the module assembler integrates upward for supply security. Independent research treats their coexistence as evidence the assembly layer itself is the scarce resource, not any one configuration. Every architecture still needs aligning.

A ranking framework is only as good as its validation record, and rank #1 provides the template. Your thread shows the ladder in action: independent supplier confirmation, analyst cross-check, then revealed-preference capital. That sequence promoted lasers from framework-asserted to operationally validated. Most ranks haven't fully climbed it yet.
