摘要
In the elliptical-hole photonic crystal fibers, when the central defect air hole is large enough, the modes will be disordered. The order of the HE11-like mode is investigated in detail based on the full vector supercell overlapping method. The degeneracy will be enhanced at the frequency where the modes begin to be disordered.
