Abstract

PURPOSE:To obtain a phototransmission line which is sutable to mass production, produced easily and has a little light scattering by arranging a substnance, which has a function of shilding from diffusion of impurity that enhances a refrectice index, on a boundary surface made of built-up optical substnances with low and high refrective indexed, and by making a heat treatment in a vacuum.
