Abstract: This talk will give a panoramic overview of some properties of spatial optical solitons, self-guided optical beams that can propagate in a bulk without a change of their profile. Both bright and dark solitons will be mentioned, as well as the recent results on the properties of solitary waves supported by parametric wave mixing in an optical medium with quadratic (due to second-harmonic generation) or cubic (due to third-hartmonic generation or four-wave mixing) nonlinear responce. Interaction of solitary waves will be discussed in more details, including the interaction of multi-component soltions and solitonic gluons, the soliton bound states and multi-humped solitons, soliton spiralling in a bulk, etc. Some experimental verifications of the soliton interactions in a photorefractive medium will be also discussed.
