Coherent launches PhotonLink integrated optics platform for AI datacenters

Coherent Corp. (NYSE: COHR) announced the launch of PhotonLink, an integrated optics platform designed to deliver complete optical solutions for AI datacenter infrastructure, according to a company press release dated Sept. 21, 2026.

The platform combines lasers, silicon photonics, specialty fibers, micro-optics and detectors into a single offering supporting co-packaged optics (CPO), near-packaged optics (NPO) and chip-to-chip connectivity architectures.

Coherent said it has more than ten CPO customer engagements and more than ten NPO engagements, with anchor customers and long-term agreements in place for both. The company also reported more than five engagements in chip-to-chip connectivity. Revenue from PhotonLink is expected to begin ramping in the fourth quarter of calendar year 2026.

"Customers need complete optical solutions, not just individual components," said Jim Anderson, Chief Executive Officer at Coherent. "Coherent is uniquely positioned to bring together the critical technologies, integrate and test the finished assemblies, and manufacture them at scale."

The platform spans four functions of the optical path — Generate, Shape, Guide and Receive — and includes indium phosphide (InP) lasers, vertical-cavity surface-emitting laser (VCSEL) arrays, isolators and photodetectors. Coherent said its manufacturing base has shipped more than 300 million InP lasers and more than one billion InP and gallium arsenide (GaAs) photodetectors to date.

The company said it is expanding its 6-inch InP and specialty fiber manufacturing capacity to support the PhotonLink product ramp. Coherent launched the platform at the European Conference on Optical Communication (ECOC) 2026 in Málaga, Spain, on Sept. 21.
