In this article, a novel nonlinear model is proposed to describe the permittivity of the plasma, and the nonlinear optical bistable phenomenon of the 1-D photonic crystals, which is composed of a nonlinear plasma defect layer, is theoretically investigated by the conventional transfer matrix method (TMM) under TM wave. It is figured out that the permittivity of nonlinear plasma exists in bistable state. Then, the tuning effects of the number of the photonic crystals’ (PCs) periodic layers, the incident frequency, the thicknesses of the nonlinear plasma layer, and the incident angle on the optical bistability (OB) have been emphatically studied. Additionally, the transmission and the reflectance under the influences of this bistable tuning are further proposed. The calculated results show that the adjustment of the OB can be achieved without changing the multi-layer material geometry. This multi-composite nonlinear plasma defect structure with the tunable bistable phenomenon can be applied to numerous valuable optical devices, such as novel optical power threshold devices, logic gates, and optical information memory.

本文提出了一种新的非线性模型来描述等离子体的介电常数，并通过传统的传输矩阵从理论上研究了由非线性等离子体缺陷层组成的一维光子晶体的非线性光学双稳态现象。 TM波下的方法（TMM）。发现非线性等离子体的介电常数存在于双稳态。然后重点研究了光子晶体(PCs)周期层数、入射频率、非线性等离子体层厚度和入射角对光学双稳态(OB)的调节影响。此外，还进一步提出了这种双稳态调谐影响下的透射率和反射率。计算结果表明，可以在不改变多层材料几何形状的情况下实现OB的调整。这种具有可调谐双稳态现象的多元复合非线性等离子体缺陷结构可应用于许多有价值的光学器件，例如新型光功率阈值器件、逻辑门和光学信息存储器。
