Abstract

We numerically simulated the propagation of the spiraling elliptic beam arrays in strongly nonlocal nonlinear media, and found that when the total input power is equal to the critical power and the coefficient of the cross-phase term is equal to its critical value, all the component beams can keep their widths fixed and in the soliton state. The trajectories, critical powers, and periods of the spiraling elliptic solitons all vary with the increasing of ellipticity. Furthermore, the evolution (including trajectories, width and periods) of the spiraling elliptic beam arrays also can be controlled by the input power. The shape of array depends on the off-axis parameters of each constituent soliton, and the same array can present various periodically varying propagations by tuning the initial chirp parameters. Some typical examples are numerically simulated for graphically displaying the possibility of controlling and the stability of propagation.
