Abstract
Provided is an optical pulse-generator and an optical pulse-generating method which are capable of generating an optical pulse train with an arbitrary pattern. An optical pulse-generator 1 includes a first optical modulator 21 configured to modulate input light using a first modulation signal SIG1 to generate optical pulses, a second optical modulator 41 configured to perform a modulation operation using a second modulation signal SIG2 synchronizing with the first modulation signal SIG1 and having a signal pattern that is set to output only specific part of the optical pulses, and a dispersion compensator 30 configured to compensate a chirp of the optical pulse output from the first optical modulator 21.
