Abstract
The variational method is used to investigate the parameter evolution characteristics of incoherent dual beams in cubicquintic competing nonlinear media. It is found that the coupling between the two soliton beams directly affect the soliton’s transmission speed and phase. The cubic and quintic competing nonlinearities are observed to have no impact on the transmission speed and amplitude of the two soliton beams, meaning that the amplitude is maintained constant during propagation. Additionally, the cubic and quintic competing nonlinearities do not influence the shift in the center position of the two soliton beams. The rate of phase change with respect to the transmission distance is shown to be linearly related to the cubic and quintic nonlinear coefficients of the medium. Both cubic and quintic competing nonlinearities are found to increase the rate of phase change with transmission distance, with quintic nonlinearity having a significantly greater effect on the phase change rate compared to cubic nonlinearity. This difference becomes more pronounced as the soliton amplitude is increased.
