ON THE TAPERED OPTICAL FIBERS WITH RADIALLY ANISOTROPIC LIQUID CRYSTAL CLAD

The paper presents an analytical investigation of a tapered core optical fiber of which the outermost section is loaded with radially anisotropic liquid crystal. The analyses are dealt with transverse modes supported in the fiber structure followed by the relative distribution of power in the different fiber sections. Preliminary dispersion characteristics of the guide are also illustrated. The results demonstrate that the TE modes transport very large amount of power in the outermost liquid crystal region --- the criteria much useful for fiber optic sensing and field coupling devices.
