INCOHERENT COLLISIONS BETWEEN ONE-DIMENSIONAL STEADY-STATE PHOTOREFRACTIVE SCREENING SOLITONS

We report the observation of collisions between mutually incoherent, o ne-dimensional, bright, steady-state photorefractive screening soliton s. Using the theory of planar dielectric waveguides together with the theory of photorefractive screening solitons, we explain how the colli sions depend on the peak intensity of the solitons and the externally applied biased held. Finally, we compare the experimental results with direct numerical simulations. (C) 1996 American Institute of Physics.
