JX Advanced Metals (TYO:5016) will invest roughly 3.3 billion yen to expand InP (indium phosphide) substrate production at its Isohara Plant, raising capacity by about 50% from 2025 levels, according to a Wednesday filing on the Tokyo Stock Exchange.
The move responds to surging demand for optical communication components and next-generation photonic-electronic technologies driven by data center growth and generative AI.
