Abstract :
A reflective all-optical switching based on a metallic slab coated by nonlinear optical materials with sinusoidal topography has been proposed and numerically investigated. The calculation shows the dependence of signal light intensity on the pump light intensity is a clear bistable curve, which results in a significant switch effect. This configuration shows a great advantages of simpler structure, lower requirement of pump light intensity, and higher contrast ratio of signal light.
