| Abstract: | The performance and efficiency of erbium-doped fibers pumped in the 800-nm band has been analyzed using a quantitative amplifier model. Both a silica and a fluorophosphate host were investigated. The analysis showed that under optimized conditions the fluorophosphate is superior to the silica with higher gain and up to 60% higher quantum conversion efficiency. Only with respect to noise figure is the fluorophosphate poorer because of the shorter lifetime of the metastable state. |
