Abstract

Abstract:

In order to restrict the instability of (2+1)-dimensional spatial optical soliton by the parameter control along the longitudinal axes, (2+1)-dimensional spatial optical soliton in parameter control was discussed, by solving the (2+1)-dimensional nonlinear Schr?dinger equation with variable coefficients numerically. The results show that the parameter control, namely, the combined effects of periodically controlling both the diffraction parameter and the self-focusing parameter along the longitudinal axes, can restrict the instability of (2+1)-dimensional spatial optical soliton to some extent. On the other hand, further simulations indicate that the propagation of (2+1)-dimensional spatial optical soliton in parameter control is less sensitive to both loss and finite perturbations, such as white noise. This reveals that (2+1)-dimensional spatial optical soliton in parameter control should be stable.
