Projections indicate that by 2030, the global market size for optical communication chips will exceed $11 billion, boasting an annual compound growth rate of 17%. The primary drivers of this growth are the burgeoning demand for data centers and AI computing power. In the fiercely competitive global landscape of laser and optical communication chips, R&D investment stands as the linchpin. Domestic players like Changguang Huaxin and Shijia Photonics have made significant technological strides, thanks to their substantial R&D expenditures, thereby breaking some of the foreign monopolies. Simultaneously, international giants such as Lumentum are concentrating their R&D efforts on high-end domains to sustain their technological supremacy.
