Description
微型偏振控制器
三环机械式偏振控制器是一种精度稍低的全光纤结构的偏振控制器。利用应力产生的双折射效应,从而改变光纤中透射光的偏振方向。通过沿着三个独立的缠绕盘环绕光纤,在设计波长下使用该控制器时,它的三个环分别类似于四分之一波片、半波片和四分之一波片。三环机械式偏振控制器将这三个分数波片级联起来,进行适当的角度调整就可以将任意输入偏振态转换成任意输出偏振态。其中,第一个四分之一波片将输入偏振态转化为线性偏振态。半波片旋转线性偏振态,最后四分之一波片将线性偏振态转变为任意偏振态。该产品使用简单,性能可靠,适用于裸光纤或900um光纤,在保偏器件测试和保偏光学研究领域有非常重要的应用。
