    "abstract": "The six-fold rotational symmetry of photonic crystal fibers has important\nmanifestations in the radiated fields in terms of i) a focusing phenomena at a\nfinite distance from the end-facet and ii) the formation of low-intensity\nsatellite peaks in the asymptotic far field. For our study, we employ a surface\nequivalence principle which allows us to rigorously calculate radiated fields\nstarting from fully-vectorial simulations of the near field. Our simulations\nshow that the focusing is maximal at a characteristic distance from the\nend-facet. For large-mode area fibers the typical distance is of the order 10\nLambda with Lambda being the pitch of the triangular air-hole lattice of the\nphotonic crystal fiber.",
