Abstract
Methods and systems for transient gain cancellation at an optical amplifier may involve generating saturating light that is introduced in a reverse direction to a transmission direction at a doped fiber amplification element. The doped fiber amplification element may amplify an input optical signal having a plurality of wavelengths as well as the saturating light. The saturating light may be regulated by a control circuit to counteract transient gain effects of add/drop events in the input optical signal. The saturated light may be filtered to achieve a desired spectral profile.
