Abstract
Provided is a semiconductor optical integrated circuit which consumes less electric power than a conventional semiconductor optical integrated circuit. A semiconductor optical integrated circuit () includes a semiconductor layer () in which (i) an optical waveguide (LG) including heated section Ithrough Iand (ii) heater parts Hand Hare provided. The optical waveguide (LG) meanders such that the heated sections Ithrough Iare juxtaposed to one another. Each heater part Hi is arranged between a heated section Ii and a heated section Ii+1 which are adjacent to each other.
