Abstract
PURPOSE:To readily make the low loss plane optical guide by letting glass material of high volatility contained in the glass layer of a high refractive index evaporate by an electron beam thereby forming low refractive index parts. CONSTITUTION:A high refractive index layer 21 diffused with thallium oxide or the like of high volatility is formed through ion diffusion or the like on a low refractive index sodium borosilicate glass substrate 22. When an electron beam 31 is radiated locally to this layer 21, the high volatility thallium oxide having been diffused evaporates to form low refractive index parts 34..., thus the low loss plane optical guide 35 is readiliy formed by the high refractive index layer encircled by the low refractive index parts 34....
