Abstract: Structures for a photonics chip that enable external communication and methods of forming such structures. The structure comprises a spot-size converter, a body on a semiconductor substrate, and a dielectric layer on the semiconductor substrate. The body includes a surface adjacent to the spot-size converter and a reflector on the surface. The dielectric layer includes a recess disposed above the spot-size converter and the reflector.

Abstract: The present disclosure relates to systems, methods, and non-transitory computer readable media that provide a trajectory-based explainability framework for reinforcement learning models. For example, the disclosed systems generate trajectory clusters from trajectories utilized to train a reinforcement learning agent. In some embodiments, the disclosed system generates a complementary target data set by removing a target trajectory cluster from the trajectory clusters. In some cases, the disclosed system trains a test reinforcement learning agent utilizing the complementary target data set and generates a cluster attribution by comparing the result of the test reinforcement learning agent with the result of the reinforcement learning agent.
