摘要：
Disclosed is an optical integrated circuit for heterodyne detection. The optical integrated circuit comprises: a semiconductor substrate; an active region of a semiconductor laser; two optical waveguides; a photo detector; and an optical coupler composed of the waveguides. The emission of light from the active region of the semiconductor laser is synthesized as local oscillation light with the transmission light. The synthesized light travels through the optical coupler and is detected by the photo detector.
