Abstract

One-dimensional quaternary photonic crystal (ABCD)\(^{N}\) stacked by four kinds of single-negative materials is proposed, and the multichannel filtering properties of the structure (ABCD)\(^{N}\) is investigated using the transfer matrix method. The result shows that a type of photonic gap named s-zero-\(\phi _{\mathrm {eff}}\) gap that is similar to the zero-\(\phi _{\mathrm {eff}}\) gap is found in the photonic structure. The multichannel filtering properties of the structures can be controlled by varying the period number, layer thickness, permittivity (\(\varepsilon )\) and permeability (\(\mu )\). Moreover, the angular response of the filter is analyzed, which indicates that the bandgap of the structure is independent of the incident angle at the frequency is under 1.1 GHz. Thus it provides a new way to design tunable omnidirectional and angle-sensitive multichannel filters for the applications in optical filters based on PCs.

含单负材料的四元光子晶体的多通道滤波特性

摘要

一维季光子晶体（ABCD）\（^ {N} \）由4种单负极材料的堆叠，提出和多信道过滤结构（的性质ABCD）\（^ {N} \）进行了研究使用转移矩阵法。结果表明，一种名为s-zero- \（\ phi _ {\ mathrm {eff}} \）的光子间隙类似于零- \（\ phi _ {\ mathrm {eff}} \）的光子间隙。在光子结构中发现了间隙。可以通过更改周期数，层厚度，介电常数（\（\ varepsilon）\）和磁导率（\（\ mu）\）来控制结构的多通道过滤属性。。此外，分析了滤波器的角度响应，这表明该结构的带隙与频率在1.1 GHz以下的入射角无关。因此，它为基于PC的光学滤波器中的应用提供了一种设计可调谐的全向和角度敏感型多通道滤波器的新方法。
