Single-mode operation regime for 12-fold index-guiding quasicrystal optical fibers

We have studied the extent of the single-mode operation regime for high symmetric index-guiding quasicrystal fibers by analyzing the validity of the effective V parameter, which is used to determine the single-mode cutoff for photonic crystal fibers. We demonstrate that this parameter can also be applied, without any approximations, to a high symmetric 12-fold Stampfli quasicrystal made of silica. We explain this result in terms of both intrinsic-quasicrystal defect and photonic crystal constituent units. We also analyze the extent of the second-order mode operation to further confirm the cutoff between the single- and multimode operations.
