摘　　要：偏振控制器在相干光纤通信、高速光纤通信以及光纤传感等领域具有十分重要的作用,由于要求它具有高的控制精度,因此对偏振控制器进行误差分析是必要的。文章针对HQQ型偏振控制器的波长相关性进行了误差分析,并通过仿真得到了输出偏振态的方位角和椭率角随波长变化的关系,这一结论对我们进行偏振控制器误差补偿有重要的意义。Error analysis for polarization controllers with high accuracy is necessary as they are very important in high rate optical fiber communication systems, coherent optical fiber communication systems and fiber-optic sensor systems. In this paper, error analysis is performed on the wavelength correlativity of HQQ-type polarization controller and the changes of the azimuth angle and ellipticity angle of the output polarization state with the wavelength are observed by simulation. This result is very important for the error compensation of the controller.
