Polarization-Dependent Elliptical and Rectangular Mie Voids

Abstract

Polarization is a key element in the design of nanophotonic devices, such as metasurfaces. It can be used as a parameter to change the performance of an optical device, for example, its transmission spectrum, or in conjunction with tailored anisotropies in nanostructures to control the geometric phase. To design polarization-sensitive nanophotonic systems, we therefore require anisotropic elements with tailored optical properties. Mie voids, which take the form of lower-index inclusions in a higher-index material, have exhibited unique optical properties, such as the confinement of light in air at visible and ultraviolet wavelengths. In this study, we introduce anisotropy to this system to c..
