title: Characteristics of dual-shape core fiber with an alpha-index center core.
abstract: The bending-loss and dispersion-sensitivity characteristics of a dispersion-shifted dual-shape core fiber with an alpha index center core are described. Calculations show that these characteristics can be improved by decreasing a and that a bend-optimized, dual-shaped core fiber exhibits a small bending loss and a large mode field diameter.
