Abstract: The dispersive characteristics of a photonic crystal fiber
enhanced with a liquid crystal core are studied using a planewave expansion
method. Numerical results demonstrate that by appropriate design such
fibers can function in a single-mode/single-polarization operation, exhibit
high- or low- birefringence behavior, or switch between an on-state and an
off-state (no guided modes supported). All of the above can be controlled
by the application of an external electric field, the specific liquid crystal
anchoring conditions and the fiber structural parameters.
