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 investigations. There is considerable 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 cobalt-60 γ-ray radiation up to 1 megagray (MGy) absorbed dose on silicon photonic devices. We do not find any systematic impact of radiation on passivated devices, indicating the durability of passivated silicon devices under harsh conditions.
近年来，硅光子平台迅速成熟，不仅实现了光通信，还能开展从传感器应用到基础物理研究等复杂的科学实验。人们对在诸如外层空间等恶劣环境中部署基于光子学的通信和科学仪器有着浓厚兴趣，在这些环境中，辐射损伤是一个重大问题。在本研究中，我们研究了高达1兆戈瑞（MGy）吸收剂量的钴 - 60 γ射线辐射对硅光子器件的影响。我们未发现辐射对钝化器件有任何系统性影响，这表明钝化硅器件在恶劣条件下具有耐久性。
