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.11 p.application/pdfeng© Springer-Verlag 2012Pump powerEmission lineFiber laserFiber Bragg gratingLongitudinal modeinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
