Optical communication concept stocks rose across the board, Credo Technology surged nearly 8%

Jinse Finance reported that on June 17, optical communication concept stocks rose across the board. According to the news, on June 16 local time, optical communication leader Coherent held a groundbreaking ceremony for its factory expansion in Sherman, Texas, USA. The expansion aims to increase 6-inch indium phosphide (InP) wafer production capacity, providing crucial manufacturing support for high-speed optical communication devices. Currently, over 80% of indium phosphide demand comes from AI data centers. The indium phosphide laser market is expected to continue growing, including CW lasers for pluggable optical modules and CPO/NPO, as well as tunable lasers and indium phosphide PICs for coherent optical modules. According to LightCounting data, indium phosphide is the largest segment in the optical chip market, accounting for 58% of the total market in 2025 and projected to occupy 46% by 2031, approximately $690 million.
