Cubic-quartic optical solitons having quadratic-cubic nonlinearity by sine-Gordon equation approach

Ukrainian Journal of Physical Optics, Volume 22, No. 4, Year 2021

We reveal cubic-quartic optical solitons with quadratic-cubic nonlinearity for the first time. Both polarization-preserving and birefringent optical fibres are considered. The study is also extended to include the perturbation terms of Hamiltonian type. The integration algorithm adopted in the present work is the method of sine-Gordon equation.
