Analysis of amplification in a fiber ring resonator with a fabry‐perot cavity

Abstract

The placement of an Erbium‐doped Fiber Amplifier and a Fabry‐Perot cavity inside a fiber ring resonator can generate a sinusoidal modulation in the optical signal obtained. The characterization of this behavior is achieved by changing the length of the Fabry‐Perot cavity, which acts as a sensing device. A theoretical model of the optical signal modulation obtained with such configuration is also presented.
