Lightmatter

Lightmatter announced a March 16, 2026 Open Compute Project reference-architecture initiative for co-packaged optics with industry participants including Corning, Flex, Foxconn, Hyve, Keysight, Qualcomm and QCT.

Lightmatter is sampling Passage photonic products, joining NVIDIA NVLink Fusion and moving toward volume deployment in advanced AI data centers, but broad production scale is still emerging.

Lightmatter describes Passage as the first 3D-stacked silicon photonics engine connecting thousands to millions of processors, with a roadmap from near-packaged and co-packaged optics through photonic interposers to a full photonic compute stack.

Lightmatter develops photonic interconnect and optical engine systems for AI scaling, including Passage and Guide, with record bandwidth-density demonstrations.
