A new stable dual-wavelength fiber-ring laser
based on erbium-doped fiber amplification is reported. The
laser is based on ring resonators and employs fiber Bragg
gratings to select the operation wavelengths. The topology
of the laser has a significant influence in its performance: allowing an independent control of the losses for both lasing
wavelengths and achieving a low noise configuration. As a
result, it is experimentally demonstrated that both emission
lines work in single-longitudinal-mode operation and the
topology offers a better stability and higher optical signalto-noise ratios than similar configurations.
