BELLO-JIMENEZ, M; KUZIN, E.A; IBARRA-ESCAMILLA, B  and  TELLEZ-GARCIA, R. Caracterización de un amplificador de fibra dopada con erbio a partir de sus parámetros experimentales. Rev. mex. fis. [online]. 2007, vol.53, n.4, pp.289-295. ISSN 0035-001X.

In this paper we describe a method to characterize the gain of an erbium-doped fiber amplifier (EDFA) through the numerical simulation of the signal beam along the amplifier. The simulation is based on a model constituted by the propagation and rate equations for an erbium-doped fiber. The manipulation of these equations allows us to regroup the parameters present in an EDFA, which we have named the A, B, C, D parameters, and they can be obtained experimentally from an erbium-doped fiber. Experimental results show that the measurement of these parameters allow us to estimate with very good correspondence the amplifier gain.

Keywords : Erbium; Erbium-doped fiber amplifiers; optical amplifiers.
