ABSTRACT:
An optical integrated device includes an optical waveguide structure formed on a semiconductor substrate and including a plurality of first channel optical waveguide portions, an optical coupler portion and a second channel optical waveguide portion, a burying layer formed from a semi-insulating semiconductor material and burying the optical waveguide structure therein such that an upper portion thereof forms a flat face and a side portion thereof forms an inclined face having a predetermined angle with respect to the semiconductor substrate, and a plurality of dummy structure bodies provided over a desired region in the proximity of at least an output side of the optical coupler portion so that radiation light from the optical coupler portion is spatially separated from signal light propagating along the second channel optical waveguide portion. The plural dummy structure bodies are provided discretely so as to be buried flat by the burying layer.
