Abstract

We describe an analytic method that calculates accurately (within a 1.5-dB discrepancy with numerical models) the gain of an erbium-doped fiber amplifier. Amplified spontaneous emission (ASE) is taken into account so that the gain of ASE-saturated erbium-doped fiber amplifiers is calculated properly. It is effective for wavelength multiplexing (several signals) and for different pumping schemes (copropagating or counterpropagating or both).
