一种低串扰单芯双向光组件制造技术

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。

A low crosstalk single core bidirectional optical module

A low crosstalk single core bidirectional optical component (200) includes an input and output terminal (201), a polarization beam splitter and combiner (202), a first polarization reflector (203), a second polarization reflector (204), at least one optical signal transmitting unit (205), an optical signal receiving unit (206) and a diaphragm (207). The diaphragm (207) includes a light transmitting area (2072) and an internal light blocking area\uff08 2071), the internal light blocking area (2071) is used to block the crosstalk optical signal (210) reflected or transmitted by the polarization beam splitter (202) to the optical signal receiving unit (206); in addition, the crosstalk optical signal (2012) reflected on the end surface (20112021) is biased by providing the input / output end (201) with an angle greater than 8 degrees with the output optical signal (209) and the incident end surface (20112021) of the polarization beam splitter (202 It is transmitted off the main communication optical path, reduces the energy from the crosstalk optical signal (2102012) to the optical signal receiving unit (206), effectively improves the quality of the signal received by the optical signal receiving unit (206), and realizes the bidirectional transmission of the same wavelength or near wavelength optical signal with high signal-to-noise ratio.
