Abstract
The semiconductor optical integrated circuit has a semiconductor substrate; a pn junction part formed in the semiconductor substrate so as to continuously extend along a signal transmission route, a light emitting part formed on a part of the pn junction part; and an optical waveguide part formed continuous to the light emitting part on the pn junction part. The light emitting part supplies a drive current to the pn junction part to generate an optical signal from the pn junction part, and the optical waveguide part transmits the optical signal while amplifying the optical signal by an amplification current supplied to the pn junction part.
