ABSTRACT:
Optical waveguides of the type which include a light-transmitting core and a cladding layer on said core. The optical waveguide can be planar or cylindrical such as an optical fiber. The optical waveguide is provided with an additional coating of highly biaxial or uniaxial crystalline material with different refraction indices in different directions.
