Abstract :
A numerical model has been developed which describes the principle performance features of a 1.3 μm optical fibre amplifier, including the effects of ground state absorption (GSA), excited state absorption (ESA) and amplified spontaneous emission (ASE). The rate equations for the relevant Pr3+ energy levels are solved alongside the equations describing the propagation of the pump, signal and ASE foward and backward propagating using routines developed for the erbium doped fibre amplifier
