Metamaterial Designs for Photovoltaic and IR Focal-Plane-Imaging Array Applications
Abstract
In this work we propose several designs and techniques for collecting, refracting and guiding an incoming electromagnetic wave in the lightwave regime. We primarily make use of low permittivity anisotropic media synthesized using bilayers of plasmonic metal and dielectric. By devising hetero-junctions from a combination of rotated versions of these metamaterial media, we propose ways to concentrate light either inside the structure, or focus the power outside. Physical realizations at the optical/IR regimes are presented. The proposed designs are shown to be applicable to various scenarios including photo- and thermo-voltaics, photo-detectors, sensors and focal-plane-imaging arrays (FPAs), and optical antennas. The specific issue of power loss in FPAs is addressed using these devices.
