A glass 7 containing one or more of metal microparticles, semiconductor microparticles, transition metal ion, rare earth ion and anion with characteristic absorption in a wavelength region longer than 360nm is irradiated with a pulsed laser beam condensed at a focal point 6 preset in an inner part of the glass 7. The condensed irradiation induces change of a refractive index as well as decrease of characteristic absorption in the wavelength region longer than 360nm at the focal point 6. Such the domain is continuously formed by relatively shifting the focal point 6 with respect to the glass 7. The continuous domains serve as optical waveguides 11, 12..., since optical properties are greatly different between the irradiated part and the nonirradiated part 19.
