Improved parametric spectroscopic performance of an optical fiber doped with erbium

摘要

The erbium trivalent ions(Er~(+3)) were played an important role in the development of optical telecommunications technology in recent years. The emission of ions Er~(+3) is crucial at 1.53μm for the optical telecommunications because this emission belong to the minimum of attenuation of silica fibers used to transport information. In this work we study and we optimize the populations of the ion states erbium in optical fiber in function of experimental spectroscopic parameters. This study is based on modeling of the effects of doping based on the strength of the signal and the pump used. Indeed, we simulate the transient behavior of the different levels of erbium energy, N1, N2, and N3 respectively by using MATLAB code.
