Abstract

Based on the phase variation compensation theory, we realize an angle-insensitive mid-infrared photonic bandgap (PBG) in a one-dimensional photonic crystal (1DPC) containing single-material semiconductor hyperbolic metamaterial layers. Under proper design, the bandwidth of the angle-insensitive (omnidirectional) mid-infrared PBG can reach 2.438 \(\upmu \hbox {m}\). The designed 1DPC is a simple single-material system composed of undoped and doped InAs, which can be fabricated by the molecular beam epitaxy technology under the current experimental conditions. Besides, the angle-insensitive property of the designed mid-infrared PBG is quite robust against the layer thickness. This broadband angle-insensitive mid-infrared PBG would possess potential applications for mid-infrared quantum cascade lasers, mid-infrared gas detectors, mid-infrared photothermal imaging, and protein analysis.

包含单材料半导体双曲超材料层的一维光子晶体中的角度不敏感中红外光子带隙

摘要

基于相位变化补偿理论，我们在包含单材料半导体双曲超材料层的一维光子晶体 (1DPC) 中实现了角度不敏感的中红外光子带隙 (PBG)。在适当的设计下，角度不敏感（全向）中红外 PBG 的带宽可以达到 2.438 \(\upmu \hbox {m}\). 所设计的 1DPC 是由未掺杂和掺杂 InAs 组成的简单单材料系统，可以在当前实验条件下通过分子束外延技术制造。此外，设计的中红外 PBG 的角度不敏感特性对层厚度非常稳健。这种宽带角度不敏感的中红外 PBG 将具有中红外量子级联激光器、中红外气体探测器、中红外光热成像和蛋白质分析的潜在应用。
