title: Waveguide-dispersion characteristics of dual-shape-core dispersion-shifted fibers.
abstract: Waveguide-dispersion characteristics are discussed experimentally and numerically. The waveguide dispersions of both dual-shape-core (DSC) and graded-index types of dispersion-shifted fibers are evaluated from the measured wavelength dependence of the mode field radius. It is shown that the dispersion sensitivity to core-radius change of a bend-optimized DSC fiber is smaller than that of the graded-index dispersion-shifted fiber.
