DOI: 10.1109/jphot.2024.3432744
Abstract: Silicon photonic integrated circuits and micro-electro-mechanical systems enable the design of compact, high-performance micro-opto-electro-mechanical systems (MOEMS) gyroscopes, such as recently reported optomechanical gyroscopes. However, effective on-chip light coupling within a confined micro/nano system under vacuum… read more here.
