A tunable and switchable multi-wavelength erbium-doped fiber ring laser basedon a new type tunable comb filter is proposed and demonstrated. By adjustingthe polarization controllers, dual-function operation of the channel spacingtunability and the wavelength switching (interleaving) can be readily achieved.Up to 29 stable lasing lines with 0.4 nm spacing and 14 lasing wavelengths with0.8 nm spacing in 3 dB bandwidth were obtained at room temperature. Inaddition, the lasing output, including the number of the lasing lines, thelasing evenness and the lasing locations, can also be flexibly adjusted throughthe wavelength-dependent polarization rotation mechanism.
