Abstract:
A semiconductor optical integrated device includes: a substrate; at least a lower cladding layer, a waveguide core layer, and an upper cladding layer sequentially layered on the substrate, a buried hetero structure waveguide portion having a waveguide structure in which a semiconductor cladding material is embedded near each of both sides of the waveguide core layer; and a ridge waveguide portion having a waveguide structure in which a semiconductor layer including at least the upper cladding layer protrudes in a mesa shape. Further, a thickness of the upper cladding layer in the buried hetero structure waveguide portion is greater than a thickness of the upper cladding layer in the ridge waveguide portion.
