摘　　要：运用非线性传输矩阵法对Sinc函数型光子晶体非线性微腔光学双稳态特性进行了理论推导与数值分析。结果表明,随着周期数的增大,或者非线性微腔位置的变动,微腔内光场强度分布不同,实现的双稳态阈值也不同;随着非线性微腔线性折射率的增大,微腔内场强减小,双稳态阈值趋于增大。The nonlinear transfer matrix method is used to study the optical bistable characteristics of Sinc function photonic crystal with nonlinear micro cavity. The results show that the field strength in the nonlinear microcavity and bistable thresholds are different with the increase of number of cycles or the change of the position of the nonlinear micro cavity. The field strength decreases in the nonlinear microcavity and the bistable threshold increases with the increase of linear refractive index of the nonlinear microcavity.
