Abstract:
A semiconductor optical function device comprising:a semiconductor substrate; a first junction structure part formed on said semiconductor substrate, said first junction structure part including a first conductivity type cladding layer, a light waveguide layer, and a second conductivity type cladding layer; a second junction structure part formed at a position separated from said first junction structure part on said semiconductor substrate, said second junction substrate part including said first conductivity type cladding layer and a second conductivity type sub-cladding layer; a first electrode formed on said first junction structure part; and a second electrode formed on said second junction structure part, wherein heights of said first electrode and said second electrode from a surface of said semiconductor substrate are substantially the same, and said first electrode and said second electrode are parallel to each other in a direction of propagation of light through said light waveguide layer.
