Abstract: A lens is formed out of semiconductor material. The semiconductor produces light which is coupled to the lens. The lens focuses the light and also minimizes refractive reflection. The lens is formed by a graded aluminum alloy, which is oxidized in a lateral direction. The oxidation changes the effective shape of the device according to the grading.
