Advances in photonics technology are simultaneously improving the performance and reducing the size and power of important communication, computing, and sensing capabilities. Innovation in the application of photonics technology is an important pillar of competitiveness in important areas of interest to the nation and to national security. The objective of this project was to survey available concepts for how to employ a photonics foundry to enable an innovative ecosystem for advanced integrated optics and electronics. This report provides background, summarizes analyses, identifies gaps, and provides a roadmap and resourcing for the foundry concept.
