ABSTRACT:
An optical waveguide device for optically coupling a semiconductor laser to an optical waveguide. An optical waveguide substrate having the optical waveguide therein is mounted on a smooth surface of a heat sink for the semiconductor laser on which surface the semiconductor laser is mounted so that a light entry end surface of the optical waveguide abuts against a light exit end surface of the semiconductor laser and that a surface of the optical waveguide substrate on the side where the optical waveguide is formed abuts against the smooth surface of the heat sink. Accordingly, accurate alignment between a light exit end of the semiconductor laser and a light entry end of the optical waveguide can be effected by a simple construction.
