    "abstract": "We consider the effective area A_eff of photonic crystal fibers (PCFs) with a\ntriangular air-hole lattice in the cladding. It is first of all an important\nquantity in the context of non-linearities, but it also has connections to\nleakage loss, macro-bending loss, and numerical aperture. Single-mode versus\nmulti-mode operation in PCFs can also be studied by comparing effective areas\nof the different modes. We report extensive numerical studies of PCFs with\nvarying air hole size. Our results can be scaled to a given pitch and thus\nprovide a general map of the effective area. We also use the concept of\neffective area to calculate the \"phase\" boundary between the regimes with\nsingle-mode and multi-mode operation.",
