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