In this Letter a fully vectorial numerical model is used to search for the construction parameters of monolithic high-contrast grating (MHCG) mirrors providing maximal power reflectance. We determine the design parameters of highly reflecting MHCG mirrors where the etching depth of the stripes is less than two wavelengths in free space. We analyze MHCGs in a broad range of real refractive index values corresponding to most of the common optoelectronic materials in use today. Our results comprise a complete image of possible highly reflecting MHCG mirror constructions for potential use in optoelectronic devices and systems. We support the numerical analysis by experimental verification of the high reflectance via a GaAs MHCG designed for a wavelength of 980 nm.
在本信函中，我们使用全矢量数值模型来寻找能提供最大功率反射率的单片高对比度光栅（MHCG）反射镜的结构参数。我们确定了条纹蚀刻深度小于自由空间中两个波长的高反射率MHCG反射镜的设计参数。我们分析了与当今大多数常用光电子材料相对应的广泛实际折射率值范围内的MHCG。我们的结果完整呈现了可能用于光电器件和系统的高反射率MHCG反射镜结构。我们通过对设计用于980nm波长的砷化镓MHCG的高反射率进行实验验证，来支持数值分析。
