| 摘 要： | In the approximation of the fast Debye relaxation of a nonlinear Kerr medium,the nonlinear finite-difference timedomain method is derived to simulate numerically the one-dimensional nonlinear photonic crystqal sandwiched by the Kerr medium.Bistable switching with a low threshold intensity of 0.01kW/cm^2 is obtained,and the corresponding refractive index change of the Kerr media is about 0.038.
