Abstract
In the approximation of the fast Debye relaxation of a nonlinear Kerr medium, the nonlinear finite-difference time-domain method is derived to simulate numerically the one-dimensional nonlinear photonic crystal sandwiched by the Kerr medium. Bistable switching with a low threshold intensity of 0.01kW/cm2 is obtained, and the corresponding refractive index change of the Kerr media is about 0.038.Keywords
