Abstract
Silicon photonic microresonator-based all-optical bistable switches and memory circuits are projected to have significant applications in future high-bandwidth data centers, telecommunications, intra-satellite optical network switches, PCIe links, and chip multiprocessor compute interconnects and caches. Recent advancements, such as NASA's deep space optical communication (DSOC) link and the European Space Agency's ORIONAS program, highlight the growing interest in high-speed optical communications for space networks. The reliability of integrated photonic waveguides in space environments, particularly under heavy ion conditions, has been studied, revealing the impact of optical transients (OSETs) on these systems. However, there is limited discussion on the effects of OSETs in integrated nonlinear silicon photonic bistable devices and circuits, which are crucial for future high-bandwidth space-based optical communication systems. To predict the system-level performance of these devices, TCAD modeling of reliability factors, including environmental temperature and OSET transients, is essential. Additionally, lab measurement data, informed by robust nonlinear material models, will be valuable for OSET radiation testing, providing a reference point for ensuring reliable operation.
