Abstract

Electromagnetic (EM) wave propagation through three-layer liquid crystal clad elliptical optical guides was investigated under the situations when those were loaded with and without conducting sheath helix structures. Due to exceptional features of liquid crystals, such as durable electro-optic behaviour as well as optical anisotropy, the presence of these greatly affects wave propagation, thereby controlling the confinement of power in guides. The present work was aimed to investigate the comparison between three-layer elliptical optical guide having radially anisotropic liquid crystal as its outer clad, and loaded with and without conducting sheath helix structure at the core-inner (dielectric) clad interface. The results reveal prudent use of the former kind (of guide) over the latter one owing to its having on-demand control over the propagation of power, and also, enhanced confinement in the outermost section for the guide. These features allow such sheath helix-loaded guides to be useful in optical sensing applications.
