Abstract
Proposed is a waveguide which is formed on a substrate ( ) of a polymer. For that purpose, provided between the substrate ( ) and the waveguide layer ( ) is an intermediate layer ( ) of an inorganic material which prevents a substantial amount of energy from penetrating into the relatively highly absorbent polymer material. That minimizes the waveguide losses.
