基于Kerr介质与光场的相互作用的Tran理论模型,利用在非线性条件下的有限时域差分法(finite-difference time-domain,FDTD)数值模拟了含Kerr介质的方形与三角形晶格的非线性光子晶体光腔的共振频率及其双稳态特性.含多个Kerr缺陷的三角形结构的非线性光子晶体光腔能产生多个共振模式,这种结构随光强变化的透射光强能在更大范围内保持在高透射率的状态.具有这种双稳性质的光子晶体为全光网络的设计提供了参考.
Based on the Tran theory model of interaction between Kerr medium and light field, the finite-difference time-domain (FDTD) method under non-linear conditions is used to simulate the non-square and triangular lattice of Kerr medium Resonance Frequency and Bistable Characteristics of a Linear Photonic Crystal Cavity The nonlinear photonic crystal cavity with a triangular Kerr defect can generate several resonant modes. The intensity of the transmitted light with this kind of structure varies with the intensity of light In a wide range to maintain high transmittance state.With this bistable nature of the photonic crystal for the all-optical network design provides a reference.
