ABSTRACT:
An optical bench is provided, as are a thin optical pickup that employs the optical bench, and a method of manufacturing the optical bench. The optical bench includes a light source for generating light for recording and reproducing information to and from an optical disc, a light source stand on which the light source is mounted, a mirror adjacent to the light source stand, and a bottom surface at a lower point than the light source stand and between the light source stand and the mirror surface. Sides of the light source stand besides the side facing the mirror are connected to the surface of the substrate by a flat sloped surface. Along the sloped surface, two electrodes for supplying power to the light source are connected to the light source stand. Since the metal wirings are formed along the sloped surface without trenches or windings between the light source stand and the silicon substrate, no disconnection of metal lines at a corner occurs.
