Abstract
An optical waveguide is disclosed with a substantially planar substrate and a waveguide layer applied to the substrate. The invention resides in that the substrate consists of a synthetic resin or of a material having a high organic proportion. This has the advantage that the high index of refraction of the inorganic waveguide layer is combined with the material properties of the synthetic resin substrate, such as, for example, breaking resistance, plastic and thermoplastic moldability, photochemical structuring ability, and others.
