Abstract

We report an L-band passively mode-locked erbium-doped fiber ring laser using the nonlinear polarization rotation technique. The center wavelength of the fiber laser can be tuned from 1575.5 to 1603.6 nm. The 458.7-fs pulses at 1603.6 nm show an 8.6-MHz pulse repetition rate. To the best of our knowledge, it is the longest wavelength for which subpicosecond pulses have been achieved so far with the nonlinear polarization rotation technique.
