Super-Fast AGC-EDFA for the Burst-Mode Systems without Gain Excursion in 20-ns and 21-dB Ramped Input

AGC-EDFA for the burst-mode signals is one of the most important devices in the next generation WDM. We have realized the AGC-EDFA without gain excursion in 20-ns and 21-dB ramped input with the high-speed VOA.
