Abstract
Provided is an optical pulse-generator capable of efficiently using by a low driving voltage an entire band of an optical frequency comb input to a chirp compensator for the formation of an optical pulse. According to a graph shown in FIG., dispersion compensation amounts (dispersion characteristics) necessary for a chirp (dispersion) compensator to efficiently compress an optical frequency comb which sinusoidally changes become an inverse of a parabolic coefficient. It is found that the dispersion compensation amount required at the center frequency is 2/π of that of a chirp being approximate to a linear chirp, and the required dispersion compensation amount increases as the frequency shift increases.
