Abstract:
An optical semiconductor device comprising a semiconductor substrate having a surface with an etched and substantially V-shaped first groove portion, an optical element having an optical axis in a direction of the first groove portion and disposed on the surface, and a lens mounted in the first groove portion,wherein the first groove portion comprises first and second opposing inclined surfaces, a bottom surface connecting the first and second inclined surfaces at a bottom of the first groove portion, and a third inclined surface oblique to the bottom surface and connecting the first and second inclined surfaces on an end of the first groove portion, wherein a second groove portion is formed in the substrate that extends in a direction perpendicular to the direction of the first groove portion, the third inclined surface extending from the second groove portion such that the third inclined surface is oblique to the second groove portion, and wherein the lens is positioned on the first and second inclined surfaces, a part of the lens protrudes in the second groove portion, and the optical element optically communicates through the lens.
