Enosemi and OpenLight Photonics demonstrate an optical link at 53 Gbps using a 53G DSP with integrated electroabsorption modulator driver, an OpenLight transmitter with heterogeneously integrated tunable lasers and electroabsorption modulators, and an Enosemi receiver with monolithically integrated photodetectors and transimpedance amplifiers. This demonstration of an optical link with leading-edge silicon photonics process nodes paves the way for future silicon photonic chips to leverage the same process integrations for next-generation systems. The demonstration was presented during the post-deadline session at the 2024 IEEE Silicon Photonics Conference.
