Abstract

An all-optical feedback loop is demonstrated which effectively suppresses slow, signal-induced gain fluctuations in Er-doped fiber amplifiers (EDFA's). Gain control is achieved by operating the amplifier in a ring laser configuration. Such a feedback loop which can be fabricated out of all-fiber passive components could be easily implemented in any system using EDFA's.
