Adiabaticity Engineered Silicon Polarization Independent 3-dB Coupler for the O-Band
IEEE Photonics Journal, 2023 We demonstrate a compact and broadband polarization independent 3-dB coupler for the O-band on silicon-on-insulator platform. Using the multi-parameter adiabaticity engineering protocol, unwanted coupling between eigenmodes in mode evolution couplers are

Analysis of orthogonal signal of dual-mass micro-machined gyroscope [PDF]
MATEC Web of Conferences, 2022 The dual-mass Silicon micro-machined gyroscope was processed by micro-fabrication technology. It could lead to quadrature coupling error and influence the output of the silicon micro-gyroscope. We select two commonly used gyroscope structures and analyze

A Review of Symmetric Silicon MEMS Gyroscope Mode-Matching Technologies
Micromachines, 2022 The symmetric MEMS gyroscope is a typical representative of inertial navigation sensors in recent years. It is different from the traditional mechanical rotor gyroscope in that it structurally discards the high-speed rotor and other moving parts to ...
