Three-dimensional spatiotemporal optical solitons in nonlocal nonlinear media
arXiv:nlin/0601054 · doi:10.1103/PhysRevE.73.025601
Abstract
We demonstrate the existence of stable three-dimensional spatiotemporal solitons (STSs) in media with a nonlocal cubic nonlinearity. Fundamental (nonspinning) STSs forming one-parameter families are stable if their propagation constant exceeds a certain critical value, that is inversely proportional to the range of nonlocality of nonlinear response. All spinning three-dimensional STSs are found to be unstable.
