Abstract

Coherent coupling between light and atoms may be exploited for conceiving a novel class of all-optical signal-processing devices without a direct counterpart in the continuous-wave regime. We show that the self-switching of ultrashort soliton pulses on resonance with a transition of doping centers in a slab waveguide directional coupler is based on nonlinear group-velocity (instead of the usual phase-velocity) changes.
