Abstract:
1. An optical waveguide integrated semiconductor optical device comprising: a semiconductor substrate having a first conductivity type; an optical active device located on said semiconductor substrate and including a first cladding layer of the first conductivity type, an active layer, and a second cladding layer of a second conductivity type, opposite the first conductivity type, stacked on said semiconductor substrate, in that order; an optical waveguide located on said semiconductor substrate, adjacent said optical active device, said optical waveguide including a first cladding layer of the first conductivity type and that is continuous with said first cladding layer of said optical active device, an optical guiding layer, and a second cladding layer, stacked on said semiconductor substrate, in that order, such that said optical guiding layer is in contact with and optically coupled to said active layer of said optical active device; and a first high resistance layer, higher in electrical resistivity than said second cladding layer, wherein
