Abstract

This paper presents for the first time to the best of our knowledge the spatiotemporal dynamics of soliton propagation through rare-earth doped fiber gain media under diverse gain conditions. Utilizing numerical simulations based on the Ginzburg-Landau equation, we show significant differences in dynamics under saturated and unsaturated gain conditions. Specifically, the spatiotemporal dynamics reveal recurring soliton creation and collapse, early filamentous soliton formation, and collision and repulsion interactions between them. These findings significantly contribute to our understanding of the fundamental behavior and applications of soliton-based systems in optical communications, fiber lasers, and nonlinear optics in general.
