Abstract Basing on the accurate Gaussian analytical solution of a pair of (1+2)D optical spatial solitons with symmetrical oblique incidence,we investigated the short-range interactions in the strongly nonlocal nonlinear media.Two solitons in close proximity can be intertraped via the strong nonlocality ,and propagate together in a stable spiral and the trajectory of mass center of solitons will deflect because of the phase difference and the ratio of the power of two solitons under the condition of momentum conservation. It is possible to find its application in planar all-optical interconnection in bulk media.We analyszed the evolution of the Poynting vector as they propagate through the strongly nonlocal media.
Key words ：
strongly nonlocal nonlinear media
