Abstract

This paper presents a multichannel terahertz absorber designed using an asymmetric one-dimensional photonic crystal featuring a defect composed of dielectric-bulk Dirac semimetal. The absorption properties of the proposed structure are theoretically analyzed by examining various configurations of the defect layer in terahertz frequency region for both transverse magnetic and transverse electric polarizations. We investigate the tuning properties of the absorption channels by varying the Fermi energy of the Dirac semimetal and the angle of incident light for different configurations. The results demonstrate that changes in the Fermi energy and incident angle significantly influence both the frequency and peak value of the absorption channels. Furthermore, the number of absorption channels increases with the addition of bulk Dirac semimetal layers in the defect region.

摘要

本文提出了一种多通道太赫兹吸收体，它是利用具有由介电块状狄拉克半金属构成缺陷的非对称一维光子晶体设计而成。通过研究太赫兹频率区域中缺陷层针对横向磁极化和横向电极化的各种配置，从理论上分析了所提出结构的吸收特性。对于不同配置，我们通过改变狄拉克半金属的费米能和入射光角度来研究吸收通道的调谐特性。结果表明，费米能和入射角的变化对吸收通道的频率和峰值均有显著影响。此外，在缺陷区域添加块状狄拉克半金属层会使吸收通道的数量增加。
