摘要: 光子晶体因其独特的电磁特性及其在光电子器件领域的广泛应用而备受关注。本文研究了由Dirac材料构成的一维对称型光子晶体在引入掺杂后的隧穿模特性。研究发现, 该光子晶体的透射谱中出现零-平均折射率、Dirac和布拉格三种光子带隙。引入掺杂后, Dirac带隙不支持隧穿模传输; 而对于零-平均折射率带隙和布拉格带隙, 随着入射光的入射角以及Dirac材料结构参数的变化, 可出现多个完全隧穿模, 并可实现模式分离、简并与模式频率间隔的多自由度调控。此外, 受界面效应及Dirac材料色散特性的影响, 光子晶体内部的电场局域在周期材料单元的界面处, 相对于掺杂层呈对称分布, 且在靠近掺杂层时强度达到峰值。

Abstract: Photonic crystals have received considerable attention due to their unique electromagnetic properties and extensive applications in optoelectronic devices. This paper investigates the tunneling mode in one-dimensional symmetric photonic crystals composed of Dirac materials with impurities. It is found that the transmission spectrum of photonic crystals exhibits three types of photonic band gaps: zero-average refractive index, Dirac, and Bragg. When impurities are introduced, the Dirac band gap does not support tunneling modes, whereas multiple complete tunneling modes emerge in the zero-average refractive index and Bragg band gaps with variations in the incidence angle of light and the structural parameters of Dirac materials, and mode separation, merging, and multi-degree-of-freedom control of mode frequency intervals can be achieved. In addition, owing to interface effects and the dispersion characteristics of Dirac materials, the electric field in photonic crystals is localized at the interfaces of the periodic material units, exhibiting a symmetric distribution relative to the defect layer and peaking near the defect layer.
