Symmetrical superfission of optical solitons in a well-type nonlocal system

The dynamical properties of fundamental and dipolar mode solitons, in the process of propagating in the well-type nonlocal system, are provided. During propagating in a deep well-type nonlocal system with a moderate width, a fundamental mode soliton splits into a pair of symmetrical sub-beams, and a dipolar mode soliton can divide into two pairs of symmetrical sub-beams. Furthermore, the propagation directions of these sub-beams can be effectively controlled by adjusting system parameters that include the well depth and well width. These properties could be applied to optical routing, all-optical switching, signal processing, and ultrafast optical communications.
