Abstract

A comprehensive study of the group-velocity dispersion of the TE, TM, and hybrid modes in a Bragg fiber is presented by showing many numerical examples. The dispersion can be represented in a simple form as the sum of the material and the waveguide dispersions under the quarter-wave stack condition. The performance of the dispersion can be well understood by relating it to the optical power confinement factor. The dispersion of the Bragg fiber is inversely proportional to the second power of its core radius. The simple dispersion formula can be conveniently used to evaluate the dispersion near the central region of the photonic band. Properties relating to the dispersion are equivalent to those of the conventional optical fibers in which all the power is confined to their core. The properties are formally the same as those in the circular metallic waveguide.
