Abstract: A functional optical device is disclosed. The optical functional device integrates a coupling unit, a light-receiving element and an optical waveguide on a semiconductor substrate. The coupling unit extracts an optical signal by interfering between signal light and local light. The optical waveguide carries the optical signal from the coupling unit to the light-receiving element. The light-receiving element receives the optical signal. The semiconductor substrate provides a heavily doped conducting layer and a buffer layer that is un-doped or lightly doped with impurities by density smaller than density of impurities in the conducting layer. The conducting layer and the buffer layer continuously and evenly expand from the optical waveguide to the light-receiving element.
