摘要
We propose a novel lasing wavelength-switchable fiber ring laser based on the gain competition between two nearby band-pass wavelengths in a homogeneously broadened erbium-doped fiber gain. The cascaded two band-pass filters are demonstrated with fiber Sagnac loop interferometers including fiber Bragg gratings and polarization controllers. The fast electrooptic interleaving operation of dual-wavelength lasing outputs can be achieved by modulating the polarization state of one band-pass filter.
