XYT- PBS/C-780

偏振分束器/合束器(780nm)



偏振分束器 / 偏振合束器(PBS / PBC)是一种基于偏振态选择性传输原理的无源光纤器件,用于将输入光中的正交偏振分量(通常为快轴 / 慢轴,或 P 光 / S 光)进行高消光比的分离,或将两路互相正交的偏振光高效率地合束到同一输出光纤中

在使用偏振光束合束/分束器时,Port 1慢轴与Port 3的对齐角度(如45°或0°)以及Port 3非偏振光从单模光纤输入的情况,代表了不同的偏振对齐和光输入方式;而端口3的非偏振光输入则是一种通用的分束方法,保偏光纤的慢轴与单模光纤中光的偏振态之间的对齐角度‌,会影响光的传输效率和合束/分束效果。
