Abstract

The modal cut-off properties of Yb-doped Double-Cladding Photonic Crystal Fibers (DC-PCFs) with 19-cell core have been analyzed considering an innovative approach, where the avoided crossing between the guided modes and the highest-index cladding mode of the real fiber is taken as the cut-off condition. A finite element-based full-vector modal solver has been applied to calculate the modes of DC-PCFs with different normalized air-hole size and core refractive index. Simulations have shown the possibility to find generalized results for the modal cut-off wavelengths of 19-cell DC-PCFs.
