DYNAMIC CHARACTERISTICS OF ALL-OPTICAL FEEDFORWARD FAST AUTOMATIC GAIN CONTROL SCHEME FOR MULTICORE ERBIUM-DOPED FIBER AMPLIFIERS

摘要

All-optical feedforward fast AGC for multicore EDFAs has been successfully achieved. The maximum absolute value of the gain excursion against the change of the number of WDM channels between 1 and 40 has been significantly reduced from 7.9 dB to 0.65 dB by using the AGC scheme proposed by us.
