Asymptotic analysis of Bragg fibers

Abstract-Analytical theory and numerical approaches to the simulation and optimal design of multilayer mirrors and optical Bragg waveguides are developed. Optimal refractive index profiles in planar and cylindrical geometry are found. Reduction of the full set of Maxwell's equations to a scalar boundary value problem in the lowcontrast approximation is discussed. An efficient finite-difference scheme is used to simulate realistic Bragg fibers.

“…Bragg fiber modes were considered as quasi mode whose propagation constant and field distribution were found by minimizing the radiation loss [1].The rising numerical error makes the field calculation very sensitive to the propagation constants. In [4][5][6][7], the periodical cladding layers of Bragg fiber were approximated by planar Bragg stack using asymptotic approximation of Bessel function; therefore Bloch theorem [8] can be used to obtain an analytical Eigen equation. In this paper we will present the design and analysis of Bragg fiber using analytical solutions for studying different modal parameters of fiber.…”

The propagation characteristics of optical fiber play a very important role in the design of a fiber optic communication system. In this paper, we have analyzed the Propagation Characteristics of Bragg fiber using transfer matrix method and have also found the modal filed distribution of the fundamental mode of Bragg fiber. We haves worked on the MATLAB and used its optical waveguide tool box for generation our results.

Abstract-An analysis of the modal propagation characteristics of a Bragg fiber having asymmetric loop boundary is made, using a simple matrix method. The boundary condition is replaced by matrix equation and the modal eigen value equation is obtained under weak guidance condition. The computed results are shown in the form of dispersion curves and cutoff frequencies and are compared with the dispersion curves of a standard Bragg fiber having circular core cross section. It is seen that the proposed Bragg fiber with a small number of claddings (two of four) shows comparable or even better performance than the standard Bragg fiber with respect to a few mode-guidance properties. 118Prajapati, Singh, and Saini
