Coherent Corp. (NYSE:COHR) is one of the Best Fiber Optics Stocks to Buy for the AI Data Center Boom. On June 16, 2026, Coherent signed a letter of intent to receive up to $50 million in CHIPS and Science Act funding from the U.S. Department of Commerce to expand its 6-inch indium phosphide semiconductor manufacturing facility in Sherman, Texas. The expansion is directly relevant to AI data centers because indium phosphide photonic devices are used in high-performance optical networking components that move data between processors, memory, switches, and systems.

Coherent said the project would double manufacturing production space and quadruple wafer production capacity, increasing domestic output of AI-enabling optical technologies. The company also said the site is home to the world’s first and largest volume-production 6-inch indium phosphide platform, giving it scale in a bottleneck area of AI interconnect supply. The project is expected to create more than 1,000 jobs, including over 550 direct manufacturing, engineering, and technical roles.
