Abstract

In this letter, the gain characteristics of the erbium-doped fiber ring amplifier at below laser threshold using a I :99 coupler, which feed back 1% ofthe output power into the ring cavity, has been studied. In the same condition, the gain of the erbium-doped fiber line amplifier has been measured, which is lower 3.2dB than that of the erbium-doped fiber ring amplifier. In the region of 1520-1570nm, the gain ofthe erbium-doped fiber ring amplifier is bigger 1.5-2.5dB than that oferbium-doped fiber line amplifier.
