Abstract

Correction methods are presented to calculate the propagation constant and group velocity dispersion of TE, TM, and hybrid modes in a Bragg fiber. The propagation constant is evaluated as a correction term from a solution derived under the quarter-wave stack condition. The group velocity dispersion is calculated by two kinds of correction methods on the basis of the above propagation constant. Both propagation constant and group velocity dispersion can be calculated using simplified algebraic equations without solving transcendental equations. Their errors and application limit are also shown.
