Abstract
An optical semiconductor device (A) includes a light reflector () and an optical semiconductor chip (). The reflector () includes two first reflecting surfaces () spaced from each other in direction x, and two second reflecting surfaces () spaced from each other in direction y. The chip () includes a rectangular upper surface and a rectangular lower surface spaced from each other in direction z perpendicular to both of the directions x and y. The chip () further includes at least one light-emitting surface () extending between the upper and the lower surfaces. The light-emitting surface () faces a corresponding one of the second reflecting surfaces (). The light-emitting surface () is non-parallel to the corresponding second reflecting surfaces () as viewed in parallel to the direction z.
