Abstract: We address surface soliton complexes formed at the edge of annular guiding structures containing several concentric rings. Such soliton complexes feature a pi-phase difference between neighboring spots. It is shown that the multipole-mode solitons can rotate steadily upon propagation, and the existence domain is strongly affected by the rotation frequency. The rotation may enhance the stabilization of surface multipole-mode solitons.
