Cubic�quartic optical solitons having quadratic�cubic nonlinearity by sine�Gordon equation approach
Ukrainian Journal of Physical Optics, 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.

Rotating asymmetric solitons in competing nonlinear media
New Journal of Physics, 2022 We predict a novel family of off-center localized nonlinear modes in a rotating optical system. The whispering-gallery-like solitons bifurcate out from the symmetric fundamental solitons through a symmetry breaking.

Application of the unified method to solve the Biswas–Arshed model
Results in Physics, 2022 We apply the unified method to retrieve optical soliton solutions of the Biswas–Arshed model (BAM) with the Kerr law nonlinearity in this paper. We first derive the ordinary differential form of this model from its partial differential form via a ...

Frequency and phase locking of laser cavity solitons [PDF]
, 2012 Self-localized states or dissipative solitons have the freedom of translation in systems with a homogeneous background. When compared to cavity solitons in coherently driven nonlinear optical systems, laser cavity solitons have the additional freedom of ...

The collision dynamics between double-hump solitons in two mode optical fibers
Results in Physics, 2021 In this paper, the coupled Manakov equations with variable coefficients, governing the orthogonally polarized pulses transmission in two mode optical fibers, are studied via the Hirota method. The double-hump one- and two-soliton solutions of the Manakov

Predicting the dynamic process and model parameters of the vector optical solitons in birefringent fibers via the modified PINN [PDF]
Chaos, Solitons & Fractals, 2021 A modified physics-informed neural network is used to predict the dynamics of optical pulses including one-soliton, two-soliton, and rogue wave based on the coupled nonlinear Schrödinger equation in birefringent fibers.

Stability of Spatial Optical Solitons [PDF]
, 2000 We present a brief overview of the basic concepts of the soliton stability theory and discuss some characteristic examples of the instability-induced soliton dynamics, in application to spatial optical solitons described by the NLS-type nonlinear models ...
