Improving long-term temperature bias stability of an integrated optical gyroscope employing a Si3N4 resonator
文献摘要：
The presence of polarization noise generated by the waveguide resonator limits the performance of a resonant integrated optical gyroscope(RIOG).Using silicon nitride(Si3N4)to fabricate a waveguide with an ultralow-aspect-ratio can result in a resonator that only supports light transmission in a single-polarization state,sup-pressing polarization noise.We successfully fabricated a Si3N4 resonator with a bending radius of 17.5 mm,a finesse(F)of 150,a quality factor(Q)of 1.54 × 107,and a propagation loss of 1.2 dB/m.The Si3N4 resonator was used to construct a double closed-loop RIOG that showed long-term bias stability(3600 s)of 13.2°/h at room temperature,14.8°/h at 40℃,21.20/h at 50℃,and 23.6°/h at 60℃.We believe this to be the best performance reported to date for a Si3N4 resonator-based RIOG.This advancement paves the way for the wider application of RIOGs.
