Vector solitons in nonlinear lattices with competing SPM and XPM terms
Liangwei Zeng, Boris A. Malomed, Dumitru Mihalache +1
We demonstrate that two-component photonic nonlinear lattices with opposite signs of the out-of-phase spatially modulated SPM and XPM coefficients can support two types of optical…
Flat-top solitons and anomalous interactions in media with even-order dispersions and competing nonlinearities
Xueqing He, Shijie Hao, Lijing Xing +3
Flat-top (FT) solitons are optical pulses that arise from the balance of dispersion and self-phase modulation in media with the competing cubic-quintic nonlinearity. Previously, FT…
Collisions and fusion of one- and two-dimensional solitons driven by potential troughs in the cubic-quintic nonlinear Schrödinger equations
Liangwei Zeng, Boris A. Malomed, Dumitru Mihalache +2
We study the formation and collision of one- and two-dimensional (1D and 2D) Gaussian-shaped and flat-top (FT) solitons in the framework of the nonlinear Schrödinger equation with…
One- and two-dimensional solitons under the action of the inverted cubic-quintic nonlinearity
Liangwei Zeng, Boris A. Malomed, Dumitru Mihalache +1
The usual cubic-quintic (CQ) nonlinearity is proved to sustain one- and two-dimensional (1D and 2D) broad (flat-top) solitons. In this work, we demonstrate that 1D and 2D soliton f…
Solitons in composite linear-nonlinear moiré lattices
Liangwei Zeng, Boris A. Malomed, Dumitru Mihalache +2
We produce families of two-dimensional gap solitons (GSs) maintained by moiré lattices (MLs) composed of linear and nonlinear sublattices, with the defocusing sign of the nonlinear…
Generation of stable multi-vortex clusters in a dissipative medium with anti-cubic nonlinearity
Y. Qiu, B. A. Malomed, D. Mihalache +3
We demonstrate the generation of vortex solitons in a model of dissipative optical media with the singular anti-cubic (AC) nonlinearity, by launching a vorticity-carrying Gaussian…
