Abstract
A novel multiwavelength erbium-doped fiber laser (EDFL) based on two comb filters is proposed and demonstrated. One comb filter is used to define the wavelength spacing, the other 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. The measured power fluctuation of each wavelength is less than 0.4 dB.
