摘要
Erbium doping introduces a resonant contribution to the group-velocity dispersion of the amplifier host fiber. A method for evaluating the erbium-induced group-velocity dispersion is proposed. This dispersion method requires the knowledge of the cold-cavity loss along with the gain and absorption spectrum of the active medium. An experimental measurement of group-velocity dispersion in a tunable actively mode-locked erbium-doped fiber laser confirms the validity of the method.
