The performance of a resonator integrated optical gyroscope (RIOG) is inevitably influenced by polarization noise. In this work, the effects of temperature-dependent polarization on the performances of an integrated optical resonator (IOR) and a RIOG are formulated mathematically and analyzed. Firstly, resonant curves with different polarization extinction ratios (PERs) and different temperature fluctuations are demonstrated. The main performances of the IOR, i.e. depth and full width at half maximum (FWHM), are not only influenced by the waveguide birefringence, but also by the intensity coupling coefficient of the couplers, both of which change with the variation of temperature. Secondly, the relationship between the variation of temperature and the variation of depth, as well as the FWHM, are obtained. Thirdly, in order to evaluate the zero bias error caused by the temperature-dependent polarization, resonant asymmetry ratio (RAR) is introduced, which is strongly dependent on the temperature fluctuatio...

谐振器集成光学陀螺仪中的温度相关、偏振引起的偏置误差

谐振腔集成光学陀螺仪 (RIOG) 的性能不可避免地受到偏振噪声的影响。在这项工作中，温度相关偏振对集成光学谐振器 (IOR) 和 RIOG 性能的影响被数学公式化和分析。首先，展示了具有不同偏振消光比（PER）和不同温度波动的谐振曲线。IOR的主要性能，即深度和半峰全宽（FWHM），不仅受波导双折射的影响，还受耦合器的强度耦合系数的影响，两者都随着温度的变化而变化。其次，得到温度变化与深度变化之间的关系，以及FWHM。第三，
