Abstract

This paper presents an in-depth study of the formation and propagation of single optical pulses in photonic crystal fibers, with a particular focus on the dynamic interaction between dark pulses and bright soliton-like pulses under different dispersion conditions. The dark pulse, propagating in the normal dispersion region, interacts with the bright pulse in the anomalous dispersion region. The results demonstrate that precise adjustment of the relative phase between these two pulses leads to the formation of a stable single wave with unconventional properties. This interaction represents a novel mechanism for controlling the formation of optical pulses in nonlinear systems, opening up prospects for innovative applications in high-speed optical communications and optical signal processing. In addition, the paper examines the impact of frequency oscillation on the performance of optical communication systems, with a detailed analysis of the propagation of super-Gaussian noise pulses in single-mode fibers. Mathematical modeling shows that these pulses are subject to significant nonlinear distortions due to the interaction between scattering and nonlinear properties of the medium, such as the Kerr effect and stimulated scattering.
