Abstract :
Pump wavelength and pump power dependency of the dynamical response of spectral hole burning (SHB) in erbium-doped fiber amplifiers (EDFAs) is investigated. The experimental results show a clear dependency on pump wavelength also in the 1480-nm range. Similar to other effects in EDFAs affecting transient performance, dynamics of SHB speeds up with increasing pump power. We conclude that the pump has a significant contribution to SHB and has to be taken into account in numerical models for SHB.
