摘要：

Dynamic compensation of low-frequency (f < 1 kHz) gain fluctuations in saturated erbium-doped fiber amplifiers is demonstrated. This compensation, based on a simple feedback-loop scheme, makes it possible to reduce transient gain fluctuations efficiently across the whole amplifier bandwidth using only a low-power (approximately 2-mu-W) optical feedback signal. Such an automatic gain control technique could be advantageously applied to suppress data packet interference due to traffic bursts in multiple-access networks, as well as in the implementation of long-haul fiber systems using erbium fiber amplifiers.
