Abstract:

In this paper, we present an analysis of unsaturated erbium-doped fiber amplifiers EDFA with fiber back-ground loss and bidirectional pumping. This analysis provides an exact, closed-form expression for the amplifier gain as a function of input pump power. This model is useful to study distributed EDFAs 1,2 and to determine the optimal Er3 concentration and pumping configuration that minimizes the required pump power, as shown in this paper. In the case of forward pumping, it is also shown that a simple relation exists between the input pump power required for EDFA transparency and pump threshold, which can be usefully applied to EDFA characterization.
