摘要

In nonlinear systems, creeping solitons, a unique type of localized waveform, preserve their structure and velocity through slow growth and interaction with their surroundings. This study investigates the kinetics of creeping solitons in fiber lasers to reduce energy loss during soliton creation. The study models the nonlinear Schrödinger equation using the split-step Fourier technique to investigate parameter-dependent soliton behaviour. Important parameters like dispersion and nonlinearity are carefully changed to optimize soliton stability and energy conservation. The results show that robust soliton generation is achieved by the interaction of dispersion, nonlinearity, and boundary conditions. The study of nonlinear waves and their uses in optical systems is advanced by in-depth investigations of energy dynamics that reveal conditions for insignificant energy loss.
