Abstract

Dual resonance absorption modes realized by a graphene in one-dimensional photonic crystal heterostructure of all-hyperbolic metamaterial (HMM)-based unit cells terminated with a gold-dielectric bilayer is examined. Resonance frequencies exhibit a distinct angular dependence: they shift upward under transverse electric (TE) polarization and downward under transverse magnetic (TM) polarization as the incidence angle increases from normal incidence up to

$89^{\circ }$

. This angular response appears almost linear in both TE and TM modes, as visualized through contour plots. The effect is primarily demonstrated in the terahertz (THz) regime using Indium Phosphide (InP) and Tellurium (Te) as the constituent materials of the HMM, which exhibit metallic behavior within this frequency range. The same phenomenon is further verified separately with Indium Antimonide (InSb)/Te and Gallium Arsenide (GaAs)/Te combinations, confirming the robustness of the observed response. These findings emphasize the tunable and polarization-sensitive nature of resonances in hypercrystal systems, underscoring their potential for advanced THz photonic applications.

基于石墨烯和金层双曲超材料的一维光子晶体中模式敏感拓扑界面态双模吸收体

研究了以金介电双分子层为端部的全双曲超材料（HMM）单晶一维光子晶体异质结构中石墨烯实现的双共振吸收模式。共振频率表现出明显的角依赖性：当入射角从正入射角增加到$89^{\circ}$时，它们在横向电（TE）极化下向上移动，在横向磁（TM）极化下向下移动。这种角响应在TE和TM模式下几乎呈线性，通过等高线图可见。使用磷化铟（InP）和碲（Te）作为HMM的组成材料，该效应主要在太赫兹（THz）范围内被证明，它们在该频率范围内表现出金属行为。用锑化铟(InSb)/Te和砷化镓(GaAs)/Te组合进一步验证了同样的现象，证实了观察到的响应的鲁棒性。这些发现强调了超晶体系统中共振的可调谐和极化敏感性，强调了它们在先进太赫兹光子应用中的潜力。
