波分复用滤波光接收器

Wavelength division multiplexing filtering optical receiver

Abstract

The invention provides a wavelength division multiplexing filtering optical receiver. The wavelength division multiplexing filtering optical receiver comprises an incidence optical fiber. An optical detection chip is arranged at the end opposite to the incidence optical fiber. A diverging lens, a filtering piece and a focusing lens are sequentially arranged between the incidence optical fiber and the optical detection chip. Light beams, with different wave lengths, emitted by the incidence optical fiber are emitted to the filtering piece in parallel after passing through the diverging lens and are focused on the optical detection chip after passing through the filtering piece. The wavelength division multiplexing filtering optical receiver filters the light beams with different wavelengths at the light receiving end and is wide in application range.
本发明提供一种波分复用滤波光接收器,包括入射光纤,与入射光纤相对的一端设有光探测芯片,其中,入射光纤与光探测芯片之间依次设有发散透镜、滤波片以及聚焦透镜,从入射光纤出射的不同波长光束经过发散透镜后平行地入射到滤波片,经过滤波片的光束聚焦到光探测芯片上。本发明提供的波分复用滤波光接收器在光接收端对不同波长的光束进行滤波,使用范围较宽。
