Abstract

A simple and effective switchable triple-wavelength Er³⁺-doped fiber laser with narrow-line-width oscillating output is proposed and demonstrated. Only using an arrayed-waveguide grating (AWG) as the comber filter and FBGs as narrow band reflectors of each F-P cavity, a stable simultaneous triple-wavelength oscillation is achieved at room temperature. The output can be switched between single- and triple-wavelength by controlling the LD pump respectively. The side mode suppression ratio and the 3-dB bandwidth of the laser’s outputs are measured to be more than 55dB and less than 10pm. Moreover, the output power stability of the laser has also been measured and analyzed.
