Abstract:
A concave diffraction grating for integrated optics is constructed by replacing the reflective metallic part by either multiple thin elements of metal or multiple elements of dielectric material, each partially reflecting the light, and arranged on elliptical fashion in order to distribute the diffraction/reflection of light and provide aberration-free focusing, by combining diffraction condition and Bragg condition of these curved reflectors.
