Abstract

The laser gain-clamped erbium-doped fiber amplifier (EDFA) is quite attractive for applications in WDM optical networks for its simple and reliable gain stabilization and equalization. A simple model describing transient dynamics of a laser gain clamped EDFA is presented in this paper. Factors governing the power excursion due to relaxation oscillations after abrupt channel dropping are examined.
