Paper Abstract

High contrast gratings (HCGs) are nowadays very popular in research due to small dimensions and their highly reflective or transmissive properties. By proper alignment of HCG bars they may become focusing reflectors or lenses. Here we present simulations of GaAs-based planar focusing reflectors realized by monolithic HCGs. We present how to design focusing reflectors and discuss how to tune their reflectivity.
