- W2367029602 abstract "An erbium-doped fiber laser(EDFL) based on a passive feedback fiber ring(FFR) and saturable absorber(SA) has been proposed,which effectively supports dual-wavelength single-longitudinal-mode(SLM) laser operation.The polarization-maintaining fiber Bragg grating(PM-FBG) is used as the wavelength selection device to produce dual-wavelength.Two 30∶70 optical couplers and a 1 m unpumped erbium-doped fiber are selected to make up the passive feedback fiber ring by calculation and simulation,which is used to increase the interval of modes and steady the laser operation.The 3 m unpumped erbium-doped fiber forms a passive self-tracking filter to ensure a stable single-longitudinal-mode fiber laser operation together with the passive feedback fiber ring.At room temperature,under 400 mW pump power,dual-wavelength single-longitudinal-mode laser is achieved,the 3 dB line widths are both less than 0.02 nm,the centre wavelengths are separately 1 545.45 nm and 1 545.90 nm,the peak power values are separately 8.158 dBm and 8.898 dBm,and the optical signal-to-noise ratio(OSNR) of output is about 60 dB.Within 3 hours,the maximum fluctuation of each peak power is less than 0.45 dB,which shows that the proposed fiber laser is quite stable.Moreover,by adjusting the polarization controller,the maximum peak power values of single-wavelength are up to 13.941 dBm and 15.432 dBm." @default.
