Bragg fibers are a kind of fiber formed by multilayer concentric cylinders with period index distribution in the radial. Since Bragg fibers have multilayer geometric characteristics, their dispersion properties are special. The effective index method (EIM) combined with multilayer waveguide theory is introduced to analyze the dispersion properties in detail, and also the scaling properties for Bragg fiber′s waveguide dispersion are gotten here. Examples are shown at last to illustrate how to design the chromatic dispersion through adjusting the Bragg fibers′ structure parameters based on the relations between the waveguide dispersion and the structure parameters.
