摘　　要：Based on the nonlinear medium transfer theory,optical bistability of nonlinear microcavity is investigated at oblique incidence.It is found that the critical frequency of incident light inducing bistability phenomenon is related to the polarization and incident angle.The critical frequency increases with the incident angle.Increasing the incident angle can make bistability happen easier for focusing Kerr medium,but will hinder bistability for defocusing Kerr medium.The bistability switch threshold of TE mode is significantly lower than that of TM mode at a large incident angle.Based on the nonlinear medium transfer theory, optical bistability of nonlinear microcavity is investigated at oblique incidence. It is found that the critical frequency of incident light inducing bistability phenomenon is related to the polarization and incident angle. The critical frequency increases with the incident angle. Increasing the incident angle can make bistability happen easier for focusing Kerr medium, but will hinder bistability for defocusing Kerr medium. The bistability switch threshold of TE mode is significantly lower than that of TM mode at a large incident angle.
