Abstract
A single mode optical waveguide which is lithographically formed and employs polymeric materials having low propagation loss. The optical waveguide has a substrate, a polymeric, buffer layer having an index of refraction n disposed on a surface of the substrate, a patterned, light-transmissive core layer having an index of refraction n disposed directly on a surface of the cladding layer, and an overcladding layer having an index of refraction n on a top surface of the core, side walls of the core, and exposed portions of the buffer layer, with n <n <n and &Dgr;n=n −n .
