Simulation design for the structures of Bragg fibers

The propagation characteristics which are influenced by the structures of Bragg fibers have been researched in this paper. Simulation software has been set up to analyze periodic structure, pseudo-periodic structure and non-axial symmetric structure for Bragg fibers. Three dimensional field distributions and the axial propagation flux characteristics which are influenced by the number of radial cladding for high and low refraction index media have been researched by computer simulation. Optimum structure simulation design has an important meaning for the manufacture of Bragg fibers.
