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.
