چکیده
Management of solitons in media with competing quadratic and cubic nonlinearities is investigated. Two schemes, using rapid modulations a mismatch parameter, the Kerr nonlinearity parameter are studied. For both cases, averaged time wave equations derived. In case management, region parameters where stabilization possible found. it shown that effective χ(2) depends on intensity imbalance between fundamental (FH) second (SH) harmonics. Predictions obtained from confirmed by numerical simulations full PDE’s.

Three-wave solitons and continuous waves in media with competing quadratic and cubic nonlinearities.
We formulate a general model of three-wave optical interactions (in the spatial domain), which combines quadratic (chi(2)) and cubic (chi(3)) nonlinearities, the latter including four-wave mixing. The model can be realized in chi(2) materials where an effective chi(3) nonlinearity is engineered by means of the quasi-phase-matching technique. Both self-focusing and self-defocusing chi(3) nonline...
متن کاملStable three-dimensional spinning optical solitons supported by competing quadratic and cubic nonlinearities.
We show that the quadratic interaction of fundamental and second harmonics in a bulk dispersive medium, combined with self-defocusing cubic nonlinearity, gives rise to completely localized spatiotemporal solitons (vortex tori) with vorticity s=1. There is no threshold necessary for the existence of these solitons. They are found to be stable if their energy exceeds a certain critical value, so ...
متن کاملStable three-dimensional optical solitons supported by competing quadratic and self-focusing cubic nonlinearities.
We show that the quadratic (chi(2)) interaction of fundamental and second harmonics in a bulk dispersive medium, combined with self-focusing cubic (chi(3)) nonlinearity, give rise to stable three-dimensional spatiotemporal solitons (STSs), despite the possibility of the supercritical collapse, induced by the chi(3) nonlinearity. At exact phase matching (beta = 0) , the STSs are stable for energ...
متن کاملNonlocal dark solitons under competing cubic-quintic nonlinearities.
We investigate properties of dark solitons under competing nonlocal cubic-local quintic nonlinearities. Analytical results, based on a variational approach and confirmed by direct numerical simulations, reveal the existence of a unique dark soliton solutions with their width being independent of the degree of nonlocality, due to the competing cubic-quintic nonlinearities.
متن کاملStabilization of vortex solitons by combining competing cubic-quintic nonlinearities with a finite degree of nonlocality
In contrast to an infinite degree of nonlocality, we demonstrate that vortex solitons in nonlinear media under competing self-focusing cubic and self-defocusing quintic nonlocal nonlinearities can be stabilized with a finite degree of nonlocality. Stable vortex solitons in the upper branch, bifurcated from the competing cubic-quintic nonlinearities, are found to be supported when the original d...
