Abstract

In this paper, by utilizing two series connected Lyot-Sagnac filter, we propose a switchable erbium-doped fiber laser (EDFL) which can be switched between single-wavelength and multi-wavelength in the experiment. The laser can realize stable single-wavelength, dual-wavelength, triple-wavelength output at room temperature by adjusting polarization orientations of two polarization controllers(PCs) in the two series connected Lyot-Sagnac filter. The optical signal-to-noise ratio (OSNR) of the laser is over 30 dB, and the peak fluctuation over 30 minute is less than 0.5 dB at room temperature.
