Abstract

In this paper we present an extensive theoretical and numerical analysis of monolithic high-index contrast grating, facilitating simple manufacture of compact mirrors for very broad spectrum of vertical-cavity surface-emitting lasers (VCSELs) emitting from ultraviolet to mid-infrared. We provide the theoretical background explaining the phenomenon of high reflectance in monolithic subwavelength gratings. In addition, by using a three-dimensional, fully vectorial optical model, verified by comparison with the experiment, we investigate the optimal parameters of high-index contrast grating enabling more than 99.99% reflectance in the diversity of photonic materials and in the broad range of wavelengths.

摘要

在本文中，我们对单片高折射率对比度光栅进行了广泛的理论和数值分析，这有助于为从紫外到中红外发射的垂直腔面发射激光器（VCSEL）的非常宽的光谱范围简单制造紧凑型反射镜。我们提供了解释单片亚波长光栅中高反射现象的理论背景。此外，通过使用经实验验证的三维全矢量光学模型，我们研究了高折射率对比度光栅的最佳参数，该参数能在多种光子材料和宽波长范围内实现超过99.99%的反射率。
