摘　　要：报导了利用光纤应力双折射效应研制的 1.55μm波长的自适应偏振控制器 ,该控制器具有自动搜索、跟踪和精确控制光纤输出偏振态的功能。经初步检测 ,当偏振态变化 3π/s时 ,输出偏振光强度为给定偏振方向分量总光强的 92 % ,平均偏差小于 2 %Utilizing stress birefringence in fiber, a developed self adapt polarization controller at 1.55μm is represented. The controller is enable to provide the functions of automatic search, tracking and fine control for the output polarization state from the fiber. As a primary measurement, the output intensity at the fixed polarization direction can be kept in 0.036dB, when the polarization states change at 3π/s. The average control error is less than 2%.
