This optical modulator is provided with a generating unit and a beam synthesizing unit. The generating unit is provided with a first generating unit and a second generating unit. The first generating unit is configured in such a manner as to provide modulation to a prescribed phase, generating a phase-modulated beam having a first light intensity. The second generating unit is configured in such a manner as to provide modulation to a prescribed phase, generating a phase-modulated beam having a second light intensity that differs from the first light intensity. The beam synthesizing unit is configured in such a manner that the two phase-modulated beams generated by the generating unit are emitted in polarization directions that are perpendicular to each other, and polarization synthesis is performed on the two phase-modulated beams, and an optical modulation signal is outputted. |
