OCP 2025
Title: High Bandwidth XSR Driven Optical Links for CPO
Presenter: Nikhil Kumar, Senior Director of Photonics
AI demands transformative interconnects for bandwidth & power. We present an industry-first validation of a commercially available, power-efficient extra-short reach (XSR) SerDes interfaced with a microring-based 8λ x 50Gbps NRZ WDM optical link through 100 meters of SM fiber. Modulator drivers & transimpedance amplifiers (TIAs) are monolithically integrated with photonics. Hardware stabilization/wavelength tracking algorithms, demonstrate robust operation and polarization handling over temperature. This demonstration also showcases Lightmatter’s multi-wavelength muxed laser source which provides stabilized wavelength and power accuracy.
Lightmatter’s electro-optical chip extends the XSR SerDes reach from centimeters to hundreds of meters. Additionally, It enables stacking advanced CMOS electronics onto silicon photonics for 3D CPO, with integrated hardware-based control to realize extreme bandwidths and high energy efficiencies in a single package.

Title: Scaling-up Next-gen AI with Optics
Presenter: Taylor Groves, Principal Solutions Architect
Growth in scale-up networking is forcing companies to move away from electrical networksand towards optical networks. In this special focus on AI, we examine how optical scale-up can benefit training and inference workloads. We explore the tradeoffs of different approaches to optical integration (LPO, CPO and 3D Integrated) and the potential role that OCP can play in driving open standards within the ecosystem.
