signal brief
Lumentum CEO Michael Hurlston warned that indium phosphide (InP), the compound semiconductor behind every datacom laser in AI data centers, is entering a supply crunch worse than the memory industry's. In remarks at the RAISE Summit reported by Tom's Hardware, Hurlston said Lumentum's five InP fabs are shipping more than 30% below what customers want, as demand from Nvidia and hyperscalers jumps from hundreds of lasers to hundreds of millions. Nvidia responded in March by investing $2B each in Lumentum and Coherent, securing capacity. The looming bottleneck means co-packaged optics and AI cluster rollouts could face delays, and component pricing could rise. Lumentum's upcoming Q3 FY26 earnings call (IR) will likely frame this supply-demand gap and guide capacity expansion plans. A small capacity addition from Lite-On's $34.3M DenseLight stake is far too little to close the near-term shortfall. This environment favors Lumentum and Coherent as constrained but essential suppliers, with pricing power and strategic backing from Nvidia.
What the sources said:
- Tom's Hardware: 'fab and material shortfall already lags 30% below customer needs as co-packaged optics demand skyrockets'
- Tom's Hardware (Hurlston): 'Between the two of us, I don't think we can service the demand that Nvidia and others are now putting on us to solve this resistance problem in the data center.'
- Tom's Hardware: 'Nvidia put $2 billion each into Lumentum and Coherent.'
- Lumentum IR: 'Q3 2026 Lumentum Holdings Inc Earnings Conference Call'
