Dependence of mode characteristics on the central defect in elliptical hole photonic crystal fibers.
Some mode characteristics are obtained by the full vector supercell overlap method that has been developed to model triangular lattice elliptical hole photonic crystal fibers regardless of whether the light is guided by total internal reflection or a photonic bandgap mechanism. When the central defect hole is large enough, the modes are disordered. Birefringence (Deltan) dependence on the central defect is discussed in detail by numerical analysis.
