ABSTRACT:
An optical device wherein an optical waveguide is formed on a dielectric substrate, the optical device includes an input part and an output part where the optical waveguide and corresponding optical fibers are connected. A stress layer is provided for at least one of the input part and the output part. The stress layer applies a stress to the optical waveguide so that an index of refraction of the optical waveguide is reduced.
