光波导法布里—帕罗调制器调制灵敏度分析

Analyse of the Modulation Sensitivity of Optical Waveguide Fabry-perot Modulator

本文推导出了以LiNbO3为衬底的光波导法布里—帕罗调制器的调制灵敏度表达式。分析了调制灵敏度与波导损耗、端面反射率的关系。讨论了入射光谱分布对调制灵敏度的影响，以及波导电极直流偏置电压对保证调制灵敏度的作用。

The modulation sensitivity formula of optital waveguide Fabry-Perot modulator on LiNbO3, crystal is given, and its relation with the waveguide's loss and end renectivity is analysed.The effect of the incident light spectrum and the waveguide electrode's DC bias voltage on the modulation sensitivity is discussed.
