ABSTRACT:
A dispersion compensator (10) that compensates dispersion occurring in an optical pulse includes a spatial filter (100) from which a pulsed light having a single peak is emitted as an autocorrelation light when a light having a strong correlation with an optical pulse to be dispersion-compensated is introduced into the spatial filter, and from which a scattered light is emitted as a cross-correlation light when a light having a weak correlation with an optical pulse to be dispersion-compensated is introduced into the spatial filter, wherein the dispersion compensator compensates dispersion occurring in the optical pulse having the strong correlation with the optical pulse to be dispersion-compensated, with the autocorrelation light treated as a dispersion-compensated optical pulse.
