Abstract:
1. An optical waveguide device comprising: a dielectric substrate; a diffused waveguide formed by thermally diffusing a high-refractive material into the dielectric substrate; and a light-receiving element which is disposed above the diffused waveguide and which receives a part of an optical wave propagating in the diffused waveguide, wherein the light-receiving element is supported by a pedestal that supports the light-receiving element above the dielectric substrate, at least part of the pedestal is formed by disposing the high-refractive material in a predetermined pattern in a vicinity of the diffused waveguide and thermally diffusing the high-refractive material at the same time as formation of the diffused waveguide, and a height of the pedestal is almost flush with a surface of the diffused waveguide.
