Analysis of characteristics of Mandelstam–Brillouin scattering in varieties of erbium optical fibers

Abstract

The research presents the results of testing the Mandelstam–Brillouin scattering parameters for several types of optical fibers doped with erbium and cerium ions. The obtained Brillouin reflectograms of different types are shown. The frequency characteristics of Brillouin scattering are drawn. Estimates of the initial values of the Brillouin frequency shift and the behavior of the reflectograms of the back reflected signal level for the studied fiber varieties are presented. A comparative analysis of the obtained parameters of various types of erbium optical fibers is carried out.
