<p>The invention provides an optical waveguide by which, where a laser device of the surface light emitting type or a light receiving device of the surface light receiving type and the optical waveguide are to be coupled to each other, even if the device is to be mounted as of the plane mounting type, the mounting form is not complicated and the production cost necessary for optical axis adjustment is not increased. A V-shaped groove is formed on a surface of a substrate, and light reflecting films for reflecting light are formed at the opposite ends of the V-shaped groove while an optical fiber is mounted in the V-shaped groove. By the construction, light is bent by the light reflecting films formed on inclined surfaces of the V-shaped groove. Consequently, in coupling between the optical fiber and a light emitting or receiving device of the surface light emitting type or the surface light receiving type, the optical semiconductor device can be mounted with a high degree of accuracy directly on the same substrate just above any of the light reflecting films with the light emitting surface or the light receiving surface thereof directed downwardly. <IMAGE></p> |
