Abstract
An optical modulation control apparatus includes an optical modulator that includes a pair of parallel optical waveguides and electrodes disposed parallel to the optical waveguides; a waveform monitoring unit that executes a predetermined waveform adjustment with respect to a waveform of an optical signal that is output after modulation by the optical modulator, and produces a monitor signal for modulation control; and a processor that executes the modulation control of the optical modulator, based on adjustment information concerning a desired waveform and the monitor signal output by the waveform monitoring unit such that the waveform of the optical signal that is output after the modulation by the optical modulator becomes a waveform adapted to the adjustment information.
