Liquid crystal optical fibers and their applications - A brief overview

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Liquid crystal optical fibers find multifarious applications owing to the distinctcharacteristic of anisotropic nature in their physical properties. Due to high opticalanisotropy, liquid crystals are greatly demanding in a wide range of applications. Further,owing to their strong electro-optic behavior, the macroscopic optical properties of liquidcrystals can be altered under the influence of external electrical field, opening therebytheir versatile usage in the area of optics and photonics. The present chapter deals with anoverview of the applications of liquid crystals in fiber optics technology. In this stream, abrief review is presented of the usefulness of liquid crystals in optical waveguidancefollowed by the discussions on the approach to analytically investigate the lightwavepropagation characteristics of liquid crystal fibers emphasizing the power confinementfactors for the guide with radial anisotropy of the liquid crystal section. It has been foundthat the transverse electric (TE) mode excitation provides relatively higher amount ofpower in the outermost liquid crystal clad, which is attributed to the radial anisotropy ofthe section. The investigation is also extended to the case of liquid crystal tapered opticalfibers with radially anisotropic liquid crystal outermost clad, and in this case too, anenhancement of power in the liquid crystal section is observed. These features essentiallyattract the usefulness of liquid crystal tapered fibers in the fabrication of coupling devicesand/or sensors. The application of liquid crystals in helical clad fibers is also touchedupon with an emphasis on the dispersion relations. Since the introduction of conductinghelical windings leaves the impact of attenuating the waves, the similar phenomenon hasalso been observed for helical clad liquid crystal fbers as the helix pitch effectivelyreduces the propagation of modes.
