Abstract
A Y-branch waveguide includes a single merging side waveguide, two branching waveguides, and a junction area waveguide provided between the merging side waveguide and the branching waveguides and formed in a tapered shape being thicker at the branching than at the merging side. The junction area waveguide and the branching waveguides are connected by two straight waveguides parallel to each other. The straight waveguides extend in the same direction as the direction of propagation of light inside the junction area waveguide, when light is injected from the merging side waveguide.
