Abstract

Integrated all-optical switching elements have the potential for fast signal processing with a bandwidth higher than that of electronic devices. One such device is a nonlinear directional coupler (NLDC). in which the intensity distribution of light at the output of two closely spaced waveguide channels is controlled by the intensity of light injected into the channels.1 Previous experimental reports have shown partial switching of light in GaAs/AIGaAs strain-induced channel waveguides,2 ultrafast all- optical switching in a dual-core glass-fiber nonlinear coupler.3
