title: Effect of liquid crystal alignment on bandgap formation in photonic bandgap fibers.
abstract: A simple analytical model is proposed to study the formation of bandgaps in liquid crystal photonic bandgap fibers. The model shows good agreement with full-vectorial plane-wave simulations. Particularly, bandgap splitting is observed due to anisotropy. If the optic axis of the liquid crystal lies perpendicular to the fiber axis, splitting of the fundamental modes of E(x) and E(y) is also observed.
