Robust propagation of two-color soliton clusters supported by competing nonlinearities.

چکیده
We reveal numerically the remarkably robust propagation of quasistationary two-color soliton clusters in media with competing quadratic and cubic nonlinearities. We predict that such clusters carrying nonzero angular momentum can propagate over any practically feasible crystal length before they decay, even in the presence of input random perturbations.

Soliton "molecules": robust clusters of spatiotemporal optical solitons.
We show how to generate robust self-sustained clusters of soliton bullets-spatiotemporal (optical or matter-wave) solitons. The clusters carry an orbital angular momentum being supported by competing nonlinearities. The "atoms" forming the "molecule" are fully three-dimensional solitons linked via a staircaselike macroscopic phase. Recent progress in generating atomic-molecular coherent mixing ...
متن کاملStable Vortex Solitons and Robust Soliton Complexes in Optical Media with Competing Nonlinearities
An overview of recent results in the field of vortex (spinning) solitons and soliton complexes composed of several fundamental (nonspinning) solitons in twoand three-dimensional optical media with competing nonlinearities is presented. It is concluded that multidimensional solitons with intrinsic topological charge are stable provided that their internal size and power (energy) are large enough...
متن کاملSpatial soliton pairs in an unbiased photovoltaic-photorefractive crystal circuit
: Optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (PR) crystal are investigated. Each crystal can be supported the spatial soliton, and at least one must be photovoltaic. The two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...
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...
متن کاملEmbedded Solitons in Second-Harmonic-Generating Systems
We present a new type of soliton, found in models characterized by opposing dispersions and competing nonlinearities at fundamental and second harmonics. They are isolated solitary waves, existing at discrete values of the propagation constant inside the system’s continuous spectrum. We show analytically, and verify by simulations, that the fundamental solitons are linearly stable. They can be ...
