ABSTRACT:
An optical semiconductor device includes a semiconductor substrate; a light receiving element formed on the semiconductor substrate; a light absorbing element formed on the semiconductor substrate and located adjacent to the light receiving element; and a semiconductor element formed on the semiconductor substrate and used for signal processing. The light absorbing element includes a fifth semiconductor layer, and a light absorption region in the light receiving element has a different structure from a light absorption region in the light absorbing element.
