This study focuses on chirped solitons in a higher-order nonlinear Schrodinger equation, investigating the effects of septicty nonlinearity and weak nonlocality on the dynamical behaviors of these solitons, and obtaining analytical bright and kink solitons.
This work focuses on chirped solitons in a higher-order nonlinear Schrodinger equation, including cubic-quintic-septic nonlinearity, weak nonlocal nonlinearity, self-frequency shift, and self-steepening effect. For the first time, analytical bright and kink solitons, as well as their corresponding chirping, are obtained. The influence of septic nonlinearity and weak nonlocality on the dynamical behaviors of those nonlinearly chirped solitons is thoroughly addressed. The findings of the study give an experimental basis for nonlinear-managed solitons in optical fibers.
