Abstract

The intensity dependent transmission characteristics of 1-D photonic crystal (PC) structure with a defect have been studied. We consider a SiO2/GaAs multilayer structure the refractive index of GaAs layer to be dependent on intensity. The refractive indices of GaAs layer is the functions of intensity of incident light. This property can be used to tune the defect modes at desired wavelength. It is found that the average change in central wavelength of defect mode is 0.08 nm/(GW/cm2 ). This property can be exploited in the design of a single channel wavelength division demultiplexer for application in optical communication..
