Abstract
The effect of ytterbium codoping in heavily erbium-doped fibers with partly clustered erbium ions on the intensity noise stemming from both pump-rate and cavity-loss fluctuations is theoretically investigated with a modified ion-cluster model. Numerical results indicate that low-frequency (below 1 M Hz) noise can be greatly suppressed by ytterbium codoping. (C) 2000 Optical Society of America.
