In this paper, the reflection characteristics of one-dimensional (1D) magnetized plasma photonic crystals (MPPCs) are studied by using the transfer matrix method. The given structure is made up of binary photonic crystals whose unit only contains two plasma layers with different plasma frequencies and a dielectric material layer at the end. The phenomenon of Fano resonance can be realized by such a simple periodic asymmetric structure. By applying the external applied magnetic field, the properties and transmission metrics of the presented MPPCs can be achieved. The numerical results reveal that two narrow and asymmetric linear reflection peaks will appear, and a phenomenon of Fano resonance can be observed. The influences of refractive index, period constant, incident angle, and magnetized plasma parameters on the obtained Fano resonance also are investigated. The analyzed results demonstrate that the tailored Fano resonance can appear in the proposed 1D MPPCs, and the above parameters can affect its features. The stated 1D MPPCs can be used in the sensors, slow light optical devices, and so on.

一维磁化等离子体光子晶体中的可调 Fano 共振

在本文中，使用传递矩阵方法研究了一维 (1D) 磁化等离子体光子晶体 (MPPC) 的反射特性。给定的结构由二元光子晶体组成，其单元仅包含两个具有不同等离子体频率的等离子体层和末端的介电材料层。Fano共振现象可以通过这样一个简单的周期性非对称结构来实现。通过施加外加磁场，可以实现所提出的 MPPC 的特性和传输指标。数值结果表明，将出现两个窄且不对称的线性反射峰，并且可以观察到Fano共振现象。折射率、周期常数、入射角、还研究了获得的 Fano 共振的磁化等离子体参数。分析结果表明，所提出的一维 MPPC 中会出现定制的 Fano 共振，并且上述参数会影响其特征。所述一维 MPPC 可用于传感器、慢光光学器件等。
