It has to be said: demand for optical chips is extremely strong.

In recent days, the global optical chip supply chain has seen a dense wave of capacity expansions, long-term agreements, investments, and supply-chain lock-ins:

  • Coherent is expanding its 6-inch InP compound semiconductor fab in Sherman, Texas.

  • Nokia is expanding advanced photonic chip testing and packaging capacity in Allentown, Pennsylvania.

  • Japan’s JX Advanced Metals plans to invest up to 120 billion yen to increase InP substrate capacity 7–10 times.

  • IQE signed a multi-year InP epi-wafer supply agreement with Tower Semiconductor.

  • China’s Suzhou Optoelectronics (under Dongshan Precision) announced a $1.2 billion optical chip and high-speed optical module expansion project in Changzhou.

A full-scale capacity race centered on AI data center optical interconnects has officially begun.
