Efforts to develop optical interfaces with Terabit capacity for datacom applications have kicked off. A practical path to the Terabit regime is to scale the current 400G modules, which are based (in the most forward looking version of the standards) on 4 parallel lanes, each operating with PAM-4 at 53 Gbaud. Scaling these modules by adding lanes looks simple, but entails challenges with respect to the fabrication and assembly complexity that can critically affect their manufacturability and cost. TERIPHIC aims to address these challenges by leveraging photonic integration concepts and developing a seamless chain of component fabrication, assembly automation and module characterization processes as the basis for high-volume production lines of Terabit modules.
