ABSTRACT:
An integrated optical waveguide device includes a substrate, and an optical waveguide which is formed in the form of projection or is formed in a trench formed in the substrate. Each optical waveguide has a first optical area made of a first optical material and a second optical area which is made of a second optical material and is surrounded by the first optical area. The optical waveguides are arranged on both side faces of the projection or trench.
