摘要
An optical receiver includes a semiconductor optical amplifier configured to amplify wavelength multiplexed light, an optical demultiplexer configured to demultiplex the wavelength multiplexed light amplified by the semiconductor optical amplifier into light of a plurality of signals having different wavelengths, a plurality of light-receiving elements configured to receive the signal light obtained by demultiplexing of the optical demultiplexer, a detector configured to detect an intensity of the wavelength multiplexed light of a previous stage of the optical demultiplexer, a memory configured to store an upper limit value of a drive current of the semiconductor optical amplifier corresponding to a detection result of the detector, and a controlling the drive current of the semiconductor optical amplifier by referring an output of the detector and the upper limit value.
