In this paper, a new theoretical model for Rayleigh backscattering (RB) analysis of fiber Raman amplifiers is proposed. The model includes all the interactions
In this paper, we extend the mapping transformation method through introducing variable coefficients.By means of the extended mapping transformation method, man
