Foundry Development of System-On-Chip InP-Based Photonic Integrated Circuits

We review the state-of-the-art in monolithic-integrated InP-based system-on-chip (SOC) photonic integrated circuits (PICs) and the extension of this capability to a foundry offering. The learnings and best practices embodied in the design and fabrication capability of commercially deployed monolithically integrated coherent optical communication SOC are leveraged to develop an optimized and scalable integration platform for a turn-key foundry process. The design automation and infrastructure required to enable a consistent reproducible InP-based foundry offering is summarized.
