Abstract
Abstract This invention concerns improved structures for the transformation of radiant energy into electric energy or vice versa. The improvement consists in coupling a solid having excited electron states with a Fresnel optical system into a compact integrated structure. The solid having excited electron states can be a semiconducting microcircuit element, or a laser material.
