As AI server interconnects advance toward 1.6T and co-packaged optics (CPO), high-power continuous-wave (CW) lasers are becoming a strategic battleground for global technology companies. At the heart of these optical engines, indium phosphide (InP) manufacturing is shifting toward larger 4-inch and 6-inch wafer production. While existing suppliers have yet to fully meet growing demand, Taiwanese c

Chinese defense supplier Harbin Xinguang Optic-Electronics Technology demo’d two man-portable anti-drone lasers at a Beijing arms expo this week.

Japanese Prime Minister Sanae Takaichi is scheduled to visit Assam in northeastern India in early July 2026. According to Nikkei, more than 50 Japanese companies and business groups, including Suzuki, Itochu and Toyota Tsusho, are expected to accompany the delegation, with market attention focused on cooperation in semiconductors and infrastructure.

AI infrastructure is increasingly dependent on light, and more of that technology is being built in Texas. Coherent's new Sherman expansion, backed by public and private funding, could strengthen global supply chains for the lasers and optical components that connect data centers, chips, and servers worldwide.

A computer vision and robotics expert has created and trained what he boasts is “the ultimate mosquito killer” using machine learning and a laser.

Facing expanding opportunities in both optical communications and satellite connectivity, Dennis Chen, chairman of WIN Semiconductors, said the company is actively advancing a range of products, including driver ICs, continuous-wave (CW) lasers, and photodiodes, while also ramping up capacity in anticipation of growing demand from next-generation networks.
