We study the effects associated with spatiotemporal light localization near the edge of a semi-infinite array of weakly coupled nonlinear optical waveguides. It was shown earlier that such a system can support the existence of a novel class of (2+1) -dimensional continuous-discrete spatiotemporal solitons, which are stable in a broad region of their parameters. We analyze the collisions between this type of spatiotemporal optical solitons and demonstrate that such collisions are strongly...[Show more]
