Abstract
Excited-state absorption measurements performed at 980 nm in erbium-doped silica fibers provide evidence that Er3+ ions undergo clustering to varying degrees, depending on glass composition. The technique employed allows a quantitative characterization of the degree of clustering. It is found that the smallest degree of clustering occurs in silica fibers co- doped with aluminum, and those prepared by the sol-gel method.
