Abstract

Theoretical studies on the velocity of gap soliton in one-dimensional GaAs/AlGaAs nonlinear photonic crystal has been presented. Velocity of gap soliton through these multilayered structures has been calculated at different intensity of controlling wave by solving Maxwell’s electromagnetic equations and using transfer matrix method. The study shows that gap solitons travel at high intensity of controlling wave and this property can be exploited to trap an optical pulse and in the design of an optical switch, active WDM coupler etc..
