Abstract

PURPOSE:To eliminate photo energy loss at the time of optical transmission by disposing upper and lower layer optical guide parts through an intermediate film, making the thickness of the intermediate layer sufficient for photo coupling of the upper and lower layers, and increasing the refractive index of the upper layer in regions other than the photo coupling region part through impurity doping.
