Incoherent collisions between one-dimensional steady-state photorefractive screening solitons

We report the observation of collisions between mutually incoherent, one‐dimensional, bright, steady‐state photorefractive screening solitons. Using the theory of planar dielectric waveguides together with the theory of photorefractive screening solitons, we explain how the collisions depend on the peak intensity of the solitons and the externally applied biased field. Finally, we compare the experimental results with direct numerical simulations.
