Strong optical spatial solitons are solitons that satisfy the strong nonlocal condition.We discuss the nonplanar interaction of a pair of (1+2)D optical spatial solitons with symmetrical oblique incidence on the basis of Snyder and Mitchell's revolutionary work［Accessible solitons.Science,1997,276(6):1538—1541］.An accurate analytical solution in Gaussian form is obtained for the first time.It is shown that rrapping of two beams in a stable spiraling is possible for a large range of parameters.The spiraling structure does not depend on the initial relative phase.The projection of the wto beam centers in the transverse coordinate plane lies always in the same ellipse.It is possible to find its applications in planar all-optical swithching and all-optical interconnection in bulk media. |
