研究了氟化聚酰亚胺波导偏振依赖性对Mach-Zehnder干涉仪开关性能的影响。MZI开关的电功率消耗取决于入射光的偏振。这种极化依赖性导致了MZI开关消光比的降低。这些结果反映了具有残余应力的氟化聚酰亚胺在硅衬底上折射率的温度依赖性的极化依赖性。利用聚酰亚胺片作为波导衬底，诱导薄膜的均匀热膨胀，可以大大提高电耗和消光比的极化依赖性。
The influence of the polarization dependence of a fluorinated polyimide waveguide on the performances of a Mach-Zehnder interferometer (MZI) switch was demonstrated.The electrical power consumption of the MZI switch depended on the polarization of an incident light.This polarization dependence induced the degradation of the extinction ratio of the MZI switch.These results reflected the polarization dependence of the temperature dependence of therefractive index of the fluorinated polyimide with residual stress on a silicon substrate. The use of a polyimide plate as a waveguide substrate, which induced the uniform thermal expansion of the film, could greatly improve the polarization dependence of the electrical power consumption and the extinction ratio.
