Abstract: Optical waveguides of the type which include a light-transmitting core and a cladding layer in 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.

Abstract: An electrooptical device is provided comprising at least one substrate, at least one pair of electrodes and at least one layer of an electrooptical material. The electrooptical material represents an optically anisotropic thin crystal film and contains molecules having aromatic rings and possessing a lattice with an interplanar spacing (Bragg's reflection) of 3.4null0.2 {acute over (null)} along one of optical axes. The electrooptical material has anisotropic refractive indices and/or anisotropic absorption coefficients that are depended on an electric field strength.
