Chaotic self-trapped optical beams produced by interaction of solitons in strongly nonlocal nonlinear medial

Abstract We demonstrate the long distance behavior of interactions of spatial optical solitons in the strongly nonlocal nonlinear media that permits several forms of stable solitons. Results show that the short-range interactions of two solitons will evolve into chaotic self-trapped optical beams, which keep the beam width nearly invariant and possess the chaotic properties denoted by the positive Lyapunov exponents and spatial decoherence. However, the dynamics of the long-range interactions of solitons are fundamentally different, which will turn to be unbounded states of the self-induced waveguide for the emission of radiation waves.
