In recent years silicon photonic platforms have undergone rapid maturation enabling not only optical communication but complex scientific experiments ranging from sensors applications to fundamental physics inquiries. There is con-siderable interest in deploying photonics-based communication and science instruments in harsh environments such as outer space, where radiation damage is a significant concern. In this study, we have examined the impact of - radiation up to 1 MGy dose on silicon photonic devices. We do not find any systematic impact of radiation on passivated devices, indicating the extreme durability of passivated silicon devices under harsh conditions
