TE and TM mode power transmission through liquid crystal clad elliptical guides

The investigation of wave propagation through three-layer optical guide, where the outermost section is comprised of radially anisotropic liquid crystal medium, was presented. The emphasis was given on the confinement of optical power corresponding to the transverse electric (TE) and transverse magnetic (TM) modes. It was found that the operation under the TE mode excitation remains more promising for optical sensing applications of these, as compared to the TM one. However, a comparison of confinements in circular and elliptical liquid crystal clad guides revealed the former one to be more useful as the enhancement of power in the liquid crystal section was found to be more significant in that case.
