Analysis of erbium-doped fiber amplifiers pumped in the /sup 4/I/sub 15/2/-/sup 4/I/sub 13/2/ band

Abstract

A theoretical model for the amplifiers predicts gain coefficients of 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… (More)
