Abstract

We study the optical response of 1D photonic crystal microcavities with Kerr nonlinear and with Kerr nonlinear and dispersive defects. By means of a transfer matrix method, Kerr nonlinear and dispersive are studied on the base of δ-function and a Lorentz oscillator model, respectively. For the systems with Kerr nonlinear defects only, the localized mode frequency depends on the localized light intensity. When incident light frequency is given, with the varying incident light intensity, the system exhibits bistability. For the systems with Kerr nonlinear and dispersive defects, it is found that the threshold intensity of nonlinear bistability is much lower than the system with Kerr nonlinear only. The low threshold intensity is useful for the applications of optical switches.
