Paper Abstract

Optical bistability with 100 ps switching time has been observed in ZnS/ZnSe stratified grating filter at room temperature for the first time. We think that the optical bistability results from the band-filling effect caused by the nonlinear absorption of the material and reflection occurred among the multilayer films. When the light intensity is larger enough. The refractive index change will be larger and the transmitted light intensity increases remarkably owing to the third order nonlinear effect of ZnS/ZnSe, so ZnS/ZnSe stratified grating is of optical bistability.
