Silicon Photonics

As the amount of data sent by satellites increases, the use of silicon transceiver technology used on the ground is being considered for use in space. However, radiation in space can adversely affect electronic devices, so it is necessary to clarify the radiation resistance of silicon photonics elements. When the high-Q silicon nanocavity we developed is irradiated with radiation, the increase in optical absorption can be quantitatively estimated. In this study, we report our evaluation of the increase in absorption loss caused by neutron irradiation in high-Q nanocavities.
