摘要： PROBLEM TO BE SOLVED: To shorten the time required for adjusting a phase of a delay interferometer to an optimum value than before.SOLUTION: In an optical receiver 101 that receives an optical signal which has been modulated by a differential M phase phase-shift modulation method, each of delay interferometers 3-1 and 3-2 is inputted with an optical signal that has been branched at a branch part 2 individually. Each of balance detectors 4A and 4B detects an output of a corresponding delay interferometer. A regeneration part 7 sequentially regenerates N-bit data based on the output of each balance detector. An error correction part 8 corrects error of the data of N-bit having been regenerated sequentially by the regeneration part 7. A phase correction part 15B, for at least a part of bit pattern, detects, based on a correction result of the error correction part 8, an erroneous discrimination rate which is a probability at which each bit pattern is erroneously discriminated to be another one or a plurality of bit patterns, and then corrects a set value of at least one phase in the delay interferometers 3-1 and 3-2 based on the detected erroneous discrimination rate of bit pattern.
