Abstract:
An optical semiconductor device, comprising:a first semiconductor chip including a light receiving element for receiving optical data in two different formats, first and second signal processing circuits for processing an output signal from said light receiving element, when input data in the first and second communication format is received, respectively, said light receiving element and said first and second signal processing circuits being integrated on the same semiconductor substrate: a resin sealing body which seals said first semiconductor chip with a light receiving face of said light receiving element oriented upward and is transparent to a prescribed wavelength of light; and a light reflecting face formed on said resin sealing body on said first semiconductor chip and crossing a normal line to a plane of a light receiving face at a prescribed angle, wherein a side wall of said resin sealing body serves as the light receiving face.
