Simulation Design for a New Non-Periodic Structure Coaxial Bragg Fiber

A new non-periodic structure of coaxial Bragg fiber has been optimum designed to improve the guided out-flux transmit characteristics. The number of cladding medium layers can be reduced by the reasonable simplify design for the non-periodic cladding structure coaxial Bragg fiber, it can achieve better field confinement than Bragg fiber in the same cladding layers structure. The structure simplification for the cladding layers is useful for the fabrication of the fiber
