ABSTRACT:
The present invention comprises a waveguide substrate and an optical waveguide disposed on the substrate, the optical waveguide having an optical waveguide region as a light transmission path, an insertion region for inserting an optical functional component having a mode field width of light propagating therein larger than that of light propagating in the optical waveguide region, and an optical connection region provided between the optical waveguide region and the insertion region to change a mode field width of light propagating therein.
