ABSTRACT:
An optical planar waveguide for conducting an optical radiation along an axis consists of a wave-conducting core that extends along the axis and a coating that extends along the axis and surrounds the core, with the coating having at least one hollow space in the solid material of the coating. The waveguide is preferably made by forming a plurality of layers and by forming recesses in one of the layers, which recesses are covered to create the hollow spaces.
