Parametrically driven pure-quartic solitons
Pengfei Li, Lijing Xing, Dongdong Wang +3
Parametrically driven solitons are self-trapped modes in various physical settings, including optics, magnetics, etc. So far, the analysis was focused on the existence, stability,…
Transformation of topological optical states via spiral modulation in fractional-diffraction systems
Dongdong Wang, Xueqing He, Rujiang Li +3
We propose a scheme for manipulations of a variety of topological states in fractional optical systems through spiral modulation of the local refraction index. An analytical approx…
Pure-quartic domain-wall solitons as topological bits for data transmission
Pengfei Li, Jun Ruan, Shilong Liu +2
Domain walls (DWs) are topological defects produced by symmetry-breaking phase transitions. Although DWs have been the subject of much work due to their fundamental physical proper…
Effects of fractional diffraction on nonlinear PT phase transitions and stability of dark solitons and vortices
Xueqing He, Mingming Zhang, Pengfei Li +2
The wave propagation under the action of fractional diffraction has recently drawn increasing attention in nonlinear optics. Here, we address the effect of fractional diffraction o…
Stabilization of Axisymmetric Airy Beams by Means of Diffraction and Nonlinearity Management in Two-Dimensional Fractional Nonlinear Schrödinger Equations
Pengfei Li, Yanzhu Wei, Boris A. Malomed +1
The propagation dynamics of two-dimensional (2D) ring-Airy beams is studied in the framework of the fractional Schrödinger equation, which includes saturable or cubic self-focusing…
Airy-Gaussian vortex beams in the fractional nonlinear-Schrödinger medium
Shangling He, Kangzhu Zhou, Boris A. Malomed +9
We address the propagation of vortex beams with the circular Airy-Gaussian shape in a (2+1)-dimensional optical waveguide modeled by the fractional nonlinear Schrodinger equation.…
