<p>An optical waveguide device for optically coupling a semiconductor laser (2) to an optical waveguide (1) is disclosed. An optical waveguide substrate (4) provided with the optical waveguide (1) therein is mounted on a smooth surface (3a) of a heat sink (3) for the semiconductor laser (2) on which surface the semiconductor laser (2) is mounted so that a light entry end surface of the optical waveguide (1) abuts against a light exit end surface of the semiconductor laser (2) and that a surface (4a) of the optical waveguide substrate (4) on the side where the optical waveguide (1) is formed abuts against the smooth surface (3a) of the heat sink (3). Accordingly, accurate alignment between a light exit end of the semiconductor laser (2) and a light entry end of the optical waveguide (1) can be effected by a simple construction. <IMAGE></p> |
