The dispersion properties of high-index core Bragg fibers are investigated by superlattice model. We have analyzed the scaling properties of waveguide dispersion, discussed the dependence of waveguide dispersion on fiber structure parameters: the core radius, radial periodicity and filling ratio of the cladding, and designed an example structure of Bragg fiber for broadband flattened dispersion at 1.55μm.
