New anisotropic crystalline thin film coating for optical devices based on side-polished fibers

Summary form only given. Recently a new nanomaterial and a method for its controllable sub-micron thin film crystallization on glass and plastic substrates have been developed by Optiva, Inc. The technology provides control of crystallographic axes of the film during coating. These films exhibit strong optical anisotropy (the difference between ordinary and extraordinary refractive indices. Thin film coating can be applied directly on surfaces of any form including planar waveguides and optical fibers. Optiva-material is composed of a mixture of molecular engineering products, where each component consists of a modified organic compound of elliptic flat dye molecules that possesses a liquid crystalline phase structure formed in solvent and based upon hydrophobic-hydrophilic interaction. We have developed a reproducible technique of Optiva film coating of side polished fibres.
