    "abstract": "We consider photonic crystal fibers made from arbitrary base materials and\nderive a unified semi-analytical approach for the dispersion and modal\nproperties which applies to the short-wavelength regime. In particular we\ncalculate the dispersion and the effective index and comparing to\nfully-vectorial plane wave simulations we find excellent agreement. We also\ncalculate asymptotic results for the mode-field diameter and the V-parameter\nand from the latter we predict that the fibers are endlessly single mode for a\nnormalized air-hole diameter smaller than 0.42, independently of the base\nmaterial.",
