Abstract
A concave diffraction grating for integrated optics is constructed by replacing the reflective metallic part by multiple thin elements of metal, each partially reflecting the light, arranged in elliptical fashion in order to distribute the diffraction/reflection of light and provide aberration-free focusing by combining the diffraction condition and Bragg condition of these curved reflectors. It results in increasing the reflection from 39% to 73%, as simulations show.
