We demonstrate spatial soliton interaction and rotation in optically induced Bessel-like photonic lattices. Particlelike circular motion as well as planetlike orbiting of two solitons is observed under different initial excitations in the ring-shaped lattices. We show that, while small rotation/oscillation of solitons can be initiated by soliton self-bending, planetlike orbiting of a "satellite" soliton can be realized by imposing an initial angular momentum from a vortex beam. Our experimental results are corroborated by numerical simulations.
我们展示了光诱导贝塞尔类光子晶格中的空间孤子相互作用和旋转。在环形晶格中，在不同的初始激发下，观察到了类似于粒子的圆形运动以及两个孤子的行星式轨道。我们表明，虽然孤子自弯曲可以引发小的旋转/振荡，但通过施加涡旋光束的初始角动量，可以实现“卫星”孤子的行星式轨道。我们的实验结果得到了数值模拟的证实。
