Abstract

See full text

An optical modulator includes a modulator that modulates an input light of light by using an input signal. The optical modulator further includes a compensation circuit that compensates the phase of a signal light in accordance with an input current, the signal light being the input light modulated by the modulator. The optical modulator further includes a detector that detects the difference between the phase of the signal light compensated by the compensation circuit and the phase of an input signal that is input to the modulator. The optical modulator further includes an adjustment circuit that adjusts, in accordance with the phase difference detected by the detector, the input current that is input to the compensation circuit.
