Abstract: An analytical model for Rayleigh scattering in fibers is presented based on a full-vector finite element method (FEM) with edge/nodal hybrid element.By using this model,the Rayleigh scattering property of F-doped and GeO2-doped high-index-core bragg fibers (HICBF) is investigated.Numerical results show that the effects of fiber structure on Rayleigh scattering in F-doped HICBF are quite opposite to that in GeO2-doped HICBF.By adjusting the cladding structure,minimized Rayleigh scattering loss (RSL) can be obtained in GeO2-doped HICBF with a certain high-index core radius.Conclusion in this paper is also suitable for other doped HICBF.
