Abstract
PURPOSE:To reduce the step gap of the intermediate layer as well as to elevate the coupling effeciency by means of establishing the refractive index of each element to a specified value in an optical coupling element to be formed fom a principal and auxiliary photoconductive wave guides, intermediate layer and so on.
