Abstract
In this work, a new configuration of a multi-wavelength erbium fiber ring laser is proposed and demonstrated experimentally by introducing a feedback fiber loop in a fiber ring cavity. Four-wavelength laser emission lines were obtained simultaneously in single-longitudinal mode operation showing a power instability lower than 0.56 dB, and an optical signal-to-noise ratio higher than 50 dB for all the emitted wavelengths. The sensing capability of the FBGs gives this source the possibility to be also used as sensor-network multiplexing scheme. The system offers a better stability and higher optical signal to noise ratios than similar configurations.
