摘要: The coupled nonlinear Schrodinger equations governing the optical pulse coupling in a directional coupler are solved numerically. numerical results show that can be back and forth efficiently between two-coupled waveguides by varying input duration. energy transfer efficiency waveguide greater than 90%. It implies pulse-width dependent all-optical switching realized coupler.
