Nonlinear switching and reshaping of slow-light pulses in Bragg-grating couplers

Ha, Sangwoo; Sukhorukov, Andrey A.


We study the propagation and switching of slow-light pulses in nonlinear directional couplers composed of two parallel waveguides, where each waveguide contains a Bragg grating. We show that by optimizing the phase shift between the Bragg gratings, one can obtain specific dispersion characteristics enabling all-optical pulse manipulation in space and in time. We demonstrate that the power-controlled nonlinear self-action of light can be used to compensate dispersion-induced broadening of...[Show more]
