Abstract :
We report on the generation of bright–dark pulse pair in a figure-eight dispersion-managed (DM) passively mode-locked fiber laser with net anomalous cavity group velocity dispersion (GVD). The nonlinear amplifying loop mirror (NALM) is employed in this configuration to allow for passively mode-locked operation. Through carefully adjusting the polarization controllers (PCs), the bright–dark pulse pair could be easily achieved. Furthermore, it is found experimentally that the pulse pair is formed due to the cross coupling between the bright and dark pulses, which are located at two different wavebands.
