Abstract:
1. An optical module comprising: a high-frequency circuit substrate; at least one optical semiconductor device mounted on said high-frequency circuit substrate; and an optical waveguide substrate arranged on said high-frequency circuit substrate, said optical waveguide substrate has a first substrate cladding having a groove for optical waveguide, said groove for optical waveguide is filled with a material of high refractive index to form a core, and said groove is covered with a resin that forms a second substrate cladding; wherein said optical waveguide substrate is formed by bonding said first substrate and said second substrate with a material of high refractive index having a refractive index higher than those of said first substrate and said second substrate; and wherein the side surface of said second substrate, which surface is reverse to the side surface bonded to said first substrate, is bonded to said high-frequency circuit substrate with a resin material.
