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…
Symmetry-breaking bifurcations of pure-quartic solitons in dual-core couplers
Pengfei Li, Liangliang Dong, Dumitru Mihalache +1
We investigate spontaneous symmetry- and antisymmetry-breaking bifurcations of solitons in a nonlinear dual-core waveguide with the pure-quartic dispersion and Kerr nonlinearity. S…
Second-harmonic generation in the system with fractional diffraction
Pengfei Li, Hidetsugu Sakaguchi, Liangwei Zeng +3
We construct a family of bright optical solitons composed of fundamental frequency (FF) and second-harmonic (SH) components in the one-dimensional (planar) waveguide with the quadr…
