Fiber Cavity Ring Down and Gain Amplification Effect

The effect of an erbium-doped fiber amplifier （EDFA） placed inside the fiber ring of a cavity ring down （CRD） configuration is studied. The limitations and advantages of this configuration are discussed, and the study of the ring-down time as a function of the current applied and gain to the EDFA is...

Summary:The effect of an erbium-doped fiber amplifier （EDFA） placed inside the fiber ring of a cavity ring down （CRD） configuration is studied. The limitations and advantages of this configuration are discussed, and the study of the ring-down time as a function of the current applied and gain to the EDFA is also presented. In this case, the power fluctuations in the output signal are strongly dependent on the cavity ring-down time with the EDFA gain.
