| Abstract: | Period-doubling of dispersion-managed solitons in an Erbium-doped fiber ring laser operating at the near zero net cavity group velocity dispersion region was experimentally observed. The generated dispersion-managed solitons of the laser are characterized by their near Gaussian spectral profiles and no sidebands. Numerical simulations verified our experimental observations and showed that the period-doubling could occur both in the positive and negative near zero net cavity group velocity dispersion regions, which suggests that the occurrence of the period-doubling is an intrinsic feature of the mode-locking fiber lasers and independent of the concrete mode-locked pulse profile. |
