Multi-wavelength erbium-doped fiber laser (EDFL) is demonstrated using a piece of a bismuth-based erbium-doped fiber (Bi-EDF) in a simple ring resonator. The proposed EDFL is able to generate up to 17 lines with a constant channel spacing of 0.41 nm at 1615.5 nm region using only a piece of 215 cm l

## Abstract We have experimentally demonstrated an allโfiber passively Qโswitched Erbiumโdoped fiber (EDF) ring laser based on nonlinear polarization rotation. By incorporating a long section of singleโmode fiber and a polarizationโdependent isolator into the EDF ring laser, the intensityโdependent
We demonstrate a multiwavelength fiber laser with ultradense wavelength spacing and ultrabroad bandwidth based on inhomogeneous loss mechanism with assistance of nonlinear polarization rotation. The inhomogeneous loss, implemented by incorporating a section of highly nonlinear fiber (HNLF) and a Sag
