Abstract

Based on a non-distributed numerical model including fiber birefringence and orthogonal mode coupling, we investigate the effects of saturable absorber (SA) parameters on the mode-locking of a realistic Erbium fiber ring laser. We compute the pulse evolution in the oscillator where the pulse properties are also affected by the intracavity polarization controller (PC). Simultaneous effect of the SA and PC parameters on the properties of the generated vector solitons are studied, and their stability against intracavity polarization perturbation at different SA parameter ranges is discussed.
