A simple concept of switchable multiwavelength erbium-doped fiber laser is successfully proposed and demonstrated. The multiwavelengths are specified by a cascaded fiber Bragg gratings. The wavelength switching can be achieved due to the polarization dependence loss induced by proper adjustment of polarization controller in ring cavity, The experiments demonstrate that the switchable lasing operation with the random combination of three wavelengths can be accomplished at room temperature, as well as with a large (~60dB) output signal to background noise ratio.
