A comparison between theoretical and experimental results of gain and ASE obtained with erbium-doped fibers (EDFs) pumped at 980 nm is presented. Parameters used for the calculations were deduced from a completely different experiment based on the study of fluorescence dynamics. The deduced parameters are not only the emission coefficents (equivalent to the emission cross-sections), but also the erbium concentration and its effective radial distribution. In the subsequent comparison of gain and amplified spontaneous emissions (ASE), a good agreement between theory and experiment is obtained. Therefore, combination of the usual theoretical model of EDFs and the characterization method that is proposed can give correct gain and ASE predictions. [ABSTRACT FROM AUTHOR] |
