Paper Abstract

Large mode area double-cladding Photonic Crystal Fibers (PCFs) with reduced cladding symmetry can provide effective suppression of high-order modes even under a significant heat load. In this work the single mode properties of different PCFs with reduced cladding symmetry are numerically compared by means of a full-vector modal solver based on the finite-element method, capable of taking into account the effects of the fiber heating. The maximum coupled pump power allowing single-mode propagation has been evaluated for each design, providing useful guidelines for further development of this kind of fibers.
