Abstract

A novel switchable multiwavelength erbium-doped fiber laser (EDFL) is proposed and demonstrated based on two comb filters. One comb filter is used to define the wavelength spacing, the other filter with a very narrow wavelength spacing is used to induce wavelength-dependent loss (WDL) effect to suppress the mode competition caused by homogeneous gain broadening of the erbium-doped fiber (EDF). As a result, triple-wavelength lasing operation with wavelength spacing of 0.8 nm has been achieved. Wavelength switching operation of the laser was also obtained by adjustment of a polarization controller (PC) in the cavity. The measured power fluctuation of each wavelength is less than 0.4 dB.
