Abstract :
The authors observe little or no accumulation of optical-power variations among wavelength-multiplexed signals as they traverse successive stages of a cooled, inhomogeneously broadened, erbium-doped fiber-amplifier cascade. The cascade instead exhibits separate automatic power regulation of each channel, decoupled from other channels, without the use of servo loops.<>
