Abstract
An optical transmitterincludes an optical phase modulatorthat performs phase modulation on a continuously oscillating light, a light intensity modulatorthat performs pulse modulation on the light on which the phase modulation is performed, to output the light as a transmission light, a first signal generatorthat generates a pulse modulation driving signal in which on and off time intervals are repeated periodically, to drive the optical intensity modulator, and a second signal generatorthat generates a saw tooth wave driving signal having an amplitude equal to an integral multiple of a driving voltage needed to acquire a modulation phase of 2π of the optical phase modulator, and having a constant period, to drive the optical phase modulator
