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.
