摘要：

Optical vortex solitons are known to be stable in a scalar nonlinear system, and they have even been observed. We now explore the effects of polarization on the vortices, and find that they are unstable in Kerr defocusing media, except when the beam is circularly polarized. Numerical simulations verify this and show remarkable beam evolution, including vortex shedding and reversal of topological charge.
