Abstract

We introduce a numerically feasible method for rigorous modeling of crossed diffraction gratings with isotropic third order nonlinear materials. The approach is based on an iterative solution of the crossed grating problem with anisotropic linear materials. Several numerical experiments are performed to demonstrate the versatility and numerical stability of our computation scheme. Resonance waveguide gratings made of isotropic cubic nonlinear materials are investigated numerically using this newly developed technique. A polarization-sensitive shift of resonance peak with variation of light intensity is numerically demonstrated.
