Patent ID: 7412148

Claim:
An optical module including: an optical component having an upper and lower surface, including a waveguide holding groove located in the upper surface of the optical component; and an optical waveguide that is optically coupled with said optical component, the optical waveguide fixed to the optical component by a bond material that is arranged between an outer lateral surface of the waveguide and sidewalls of the waveguide holding groove, wherein said waveguide holding groove has substantially a circular cross-sectional shape, and the waveguide holding groove is located in the optical component in a way to form a groove opening on the upper surface of the optical component, the groove opening formed by an intersection of the sidewalls of the groove with the upper surface of the optical component, wherein a width of the groove opening on the upper surface of the optical component is narrower than a diameter of the optical waveguide located in said waveguide holding groove, and a diameter of the optical waveguide is narrower than a diameter of the circular cross-sectional shape of the waveguide holding groove.
