Optical waveguide having an essentially planar substrate and its application

摘要

An optical waveguide having an essentially planar substrate and a waveguiding layer applied to the substrate is described. The invention consists in the substrate consisting of plastic or a material with a high proportion of organic substances. This has the advantage that the high refractive index of the inorganic wave-guiding layer is combined with the material properties of the plastics substrate, such as, for example, breaking resistance, plastic and thermoplastic deformability, capability of photochemical structuring, inter alia.
