The Open Silicon Photonics for AI Systems initiative has been established by Lightmatter and 18 other companies to standardize silicon photonics infrastructure for AI applications. Announced in March 2026, the initiative operates under the Open Compute Project and includes founding members such as Celestica, Corning, and Qualcomm Technologies.
The recently published white paper outlines a co-packaged optics (CPO) architecture to facilitate scalable Modular Hardware Systems compliant with Open Rack specifications. This architecture aims to support the transition from copper to photonics, enhancing interoperability across various hardware generations. The initiative's success could significantly influence the performance of AI infrastructure.
