利用传输矩阵法研究了按分形三分Cantor序列构成的一维超导光子晶体的传输特性。数值结果表明,与传统电介质材料构成的光子晶体的频谱不同,这种光子晶体频谱没有展现出自相似性。此外,当构成光子晶体的两种材料的光学厚度相同时,光子晶体的频谱具有明显的周期性,并且在光子带隙中间成对地出现缺陷模。这种特性可以用于设计通道滤波器。
Transmission matrix method was used to study the transmission characteristics of a one-dimensional superconducting photonic crystal composed of a fractal third-order Cantor sequence. The numerical results show that unlike photonic crystals made of conventional dielectric materials, the spectrum of such photonic crystals does not exhibit self-similarity. In addition, when the optical thicknesses of the two materials constituting the photonic crystal are the same, the spectrum of the photonic crystal has a significant periodicity and defective modes appear in pairs in the middle of the photonic bandgap. This feature can be used to design channel filters.
