    "abstract": "In this paper we evaluate the cut-off properties of holey fibers (HFs) with a\ntriangular lattice of air holes and the core formed by the removal of a single\n(HF1) or more air holes (HF3 and HF7). With the aid of finite-element\nsimulations we determine the single-mode and multi-mode phases and also find\nthe air hole diameters limiting the endlessly single-mode regime. From\ncalculations of V and W parameters we find that in general HF1 is less\nsusceptible to longitudinal non-uniformities compared to the other designs for\nequivalent effective areas. As an example we illustrate this general property\nfor the particular case of a macro-bending induced loss.",
