Improved parametric spectroscopic performance of an optical fiber doped with erbium

In recent years, the rare earth ions and primarily Er played a crucial role in the development of the technology of optical telecommunications. The Emission of erbium ions at 1.53 microns is important for optical telecommunications because this emission corresponds to minimum mitigation of silica fibers which used as purpose to transport information. At first, we study the evolution of the signal powers and the pump powers along the propagation in the optical fiber amplifier Erbium doped. In addition, we study the variation of Erbium ions concentration for different spectroscopic parameters such as signal strength with (0, 1μW, 1mW) and the power of the pump going up 200 mW.
