摘要
In an optical receiver which is compatible with a plurality of signal channels, it is difficult to receive signals properly because a variation in receiving light sensitivity of a photoelectric conversion unit occurs between a plurality of signal channels, therefore, an optical receiver according to an exemplary aspect of the invention includes an optical processing circuit processing input signal light to have been input and outputting a plurality of output signal light beams; and a plurality of photoelectric conversion means for receiving the plurality of output signal light beams respectively and outputting electric signals, wherein the photoelectric conversion means includes an avalanche photodiode which can control a multiplication factor of an output current as the electric signal by means of an applied voltage; and the avalanche photodiode operates with a driving voltage by which the output currents in the plurality of photoelectric conversion means become almost the same.
