Photonic computing company Lightmatter has launched the Open Silicon Photonics for AI Systems initiative and published a 300-page white paper alongside the coalition’s founding members in an effort to standardize silicon photonics-ready infrastructure for AI.
The initiative, which will operate as an official workstream within the Open Compute Project, was first announced in March 2026 and had ten founding members, including Celestica, Corning, Dell Technologies, Flex, Foxconn Interconnect Technology, Hyve Solutions, Keysight, Qualcomm Technologies, and Quanta Cloud Technology.
Nine additional companies have now joined the project.

According to Lightmatter, the whitepaper, called ‘Architecture Vision: Open Silicon Photonics for AI Systems,’ aims to guide the development of a shared co-packaged optics (CPO) blueprint to scale Modular Hardware System (MHS)- and Open Rack v3 (ORv3)-compliant AI clusters from 72 to more than 1,024 nodes.
