SemiAnalysis identifies Indium Phosphide (InP) lasers as a newly strategic bottleneck in AI computing infrastructure, with supply of CW DFB lasers failing to meet rising demand for near-package optical connectivity.

Claims
- InP lasers have rapidly become one of the most strategically important components in computing.
- Optical connectivity is moving progressively closer to the chip package, increasing reliance on InP laser sources.
- Every optical engine and laser source in near-package optical connectivity runs on InP lasers.
- Supply of Continuous Wave (CW) Distributed Feedback (DFB) InP lasers is not keeping up with demand.
Key quotes
Indium Phosphide (InP) LASERs are suddenly catching everyone's interest since it suddenly became one of the more strategic components in computing.
As optical connectivity moves ever closer to the package, every optical engine and laser source inevitably runs on InP LASERs.
Supply isn't keeping up with demand, particularly for Continuous Wave (CW) Distributed Feedback (DFB) LASERs which enable near-package optical connectivity.
