Abstract

PURPOSE:To eliminate photo energy loss at the time of optical transmission by disposing optical guides of upper and lower layers through an intermediate layer, making the intermediate layer thickness sufficient for photo coupling of the upper and lower layers, and making the film thickness of the upper layer at a specified value in the coupling region and larger or smaller in other regions.
