ABSTRACT:
An optical waveguide in which a groove is formed on the top surface of a substrate used as a lower clad and a core is formed in the groove, characterized in that the core is formed in such a way that the top face of the core within the groove is at a lower level than the top face of the substrate, and an upper clad may also be provided on the core, and the core is preferably formed from an organic-inorganic hybrid material.
