Abstract

Optical information processing is being recognized for its importance over a wide range of use. The recent focus has been on all-optical switching because of its ultrafast response time. One device configuration of interest is the nonlinear directional coupler. Most descriptions of switching in these systems have involved the coupled nonlinear Schroedinger equation (NLS) that describes switching usually on a picosecond time scale.
