We have designed and experimentally characterized an EDFA which possesses a wavelength-independent gain spectrum, independent of the operating level of the gain (dynamic gain flatness). In the wavelength range 1542 - 1552 nm, the gain was flat to within the experimental uncertainties of ±0.3 dB even as the gain level changed by 17 dB. The EDFA was based on a low-Al-content alumino-germanosilicate EDF. We believe that this type of EDFA, which has not been demonstrated before, can significantly simplify the design of amplified WDM transmission systems and increase the robustness of long-distance WDM transmission.
