In this paper a theoretical model for Er/sup 3+/ -doped fiber amplifiers pumped within the particular /sup 4/I/sub 13/2/ /sup 4/I/sub 15/2/ absorption band is developed. The model predicts gain coefficients around 2 dB per milliwatt of launched pump power, in close agreement with previously reported measurements. The model is also used to determine the optimal pump wavelength {lambda}/sub opt/ that maximizes the amplifier gain. It is shown that the latter is insensitive to pump detuning near {lambda}/sub opt/ = 1.48 {mu}m, within a 20 nm range, which indicates that broad-band, multimode laser diode pump sources and pumps with narrow linewidths should yield identical gain performance.
