Stable three-dimensional spinning optical solitons supported by competing quadratic and cubic nonlinearities
D. Mihalache, D. Mazilu, L. C. Crasovan +5
We show that the quadratic interaction of fundamental and second harmonics in a bulk dispersive medium, combined with self-defocusing cubic nonlinearity, give rise to completely lo…
Stable spinning optical solitons in three dimensions
D. Mihalache, D. Mazilu, L. -C. Crasovan +6
We introduce spatiotemporal spinning solitons (vortex tori) of the three-dimensional nonlinear Schrodinger equation with focusing cubic and defocusing quintic nonlinearities. The f…
Stability of spinning ring solitons of the cubic-quintic nonlinear Schrodinger equation
I. Towers, A. V. Buryak, R. A. Sammut +3
We investigate stability of (2+1)-dimensional ring solitons of the nonlinear Schrodinger equation with focusing cubic and defocusing quintic nonlinearities. Computing eigenvalues o…
Higher-order nonlinear modes and bifurcation phenomena due to degenerate parametric four-wave mixing
Kazimir Y. Kolossovski, Alexander V. Buryak, Victoria V. Steblina +2
We demonstrate that weak parametric interaction of a fundamental beam with its third harmonic field in Kerr media gives rise to a rich variety of families of non-fundamental (multi…
Quadratic solitary waves in a counterpropagating quasi-phase-matched configuration
Kazimir Y. Kolossovski, Alexander V. Buryak, Rowland. A. Sammut
We demonstrate the possibility of self-trapping of optical beams by use of quasi phase matching in a counterpropagating configuration in quadratic media. We also show the predomina…
Optical Vortex Solitons in Parametric Wave Mixing
Tristram J. Alexander, Yuri S. Kivshar, Alexander V. Buryak +1
We analyze two-component spatial optical vortex solitons supported by parametric wave mixing processes in a nonlinear bulk medium. We study two distinct cases of such localised wav…
