Paper Abstract

A physical structure constructed from stripes of a material with high refractive index that are separated with a low refractive index medium is called a high contrast grating (HCG). Here we present the simulations of long focal-length GaAs-based planar focusing monolithic HCG reflectors designed for 980 nm. We discuss how the focal spot size depends on the reflector size and how it is possible to improve the maximum value of the electric field intensity distribution.
