Abstract

一种低串扰单芯双向光组件(200)，包括一个输入输出端(201)、一个偏振分束合束器(202)、一个第一偏振反射器(203)、一个第二偏振反射器(204)、至少一个光信号发射单元(205)、一个光信号接收单元(206)和一个光阑(207)，光阑(207)包括一个透光区域(2072)和一个内部挡光区域(2071)，内部挡光区域(2071)用于阻挡偏振分束合束器(202)反射或透射至光信号接收单元(206)的串扰光信号(210)；此外，还通过提供与出射光信号(209)角度大于8度的输入输出端(201)和偏振分束合束器(202)的入射端面(2011，2021)，使在端面(2011，2021)上反射的串扰光信号(2012)偏离主通信光路传播，降低串扰光信号(210，2012)到光信号接收单元(206)的能量，有效提高光信号接收单元(206)接收到的信号的质量，实现高信噪比同波长或近波长光信号的双向传输。
