Abstract:
An optical waveguide circuit includes: a lower cladding layer formed on a substrate; a first optical waveguide formed on the lower cladding layer so as to partition the lower cladding layer into a first portion and a second portion; a second optical waveguide formed on the first portion, the second optical waveguide including a tip end portion directed toward a side face of the first optical waveguide, the tip end portion being narrowed in a tapered manner; and a third optical waveguide formed on the second portion, the third optical waveguide including a tip end portion directed toward the tip end portion of the second optical waveguide, a tip end portion of the third optical waveguide being narrowed in a tapered manner.
