TE modes in liquid crystal optical fibers embedded with conducting tape helix structure

The transverse electric (TE) behaviour of light in a doubly-clad cylindrical optical fiber loaded with radially anisotropic liquid crystal material at the outermost cladding is investigated. Moreover, this situation is studied when a conducting tape helix structure is introduced at the boundary of the isotropic dielectric core and the inner dielectric clad of the fiber. The outer clad is considered to be made of anisotropic nematic liquid crystal (NLC). Using Maxwell´s electromagnetic field equations, confinement plots are obtained for the transmitted power in each scenario, under the situation of varying core dimension, and compared. Results confirm the achievement of better confinement in the liquid crystal layer of the conducting tape helix loaded fiber, which can even be tailored by using different angle of helix pitch.
