Generation of dissipative Kerr solitons in a passive fiber Kerr resonator with a fast saturable absorber

The generation of dissipative Kerr solitons (DKSs) in a passive fiber Kerr resonator with a fast saturable absorber (SA) is studied numerically. Simulation results demonstrate the generation of DKSs in SA-based fiber Kerr resonators. The impact of the properties of an SA, including the modulation depth and the saturation power, on the performances of DKSs is studied. Our results show the existence of DKSs in SA-based passive fiber Kerr resonators, suggesting that the SA provides additional degrees of freedom to get access to the DKS regime in Kerr resonators in addition to the detuning and the pump. These findings provide guidance for the experimental realization of the generation of DKSs in SA-based fiber Kerr resonators.
