| Abstract | We study the existence and stability of dark fundamental and vortex solitons in defocusing Kerr media with an imprinted finite radial lattice. The size of dark core of solitons is determined by the scale of lattice. The existence domains of both types of solitons expand with the growth of lattice size. When the lattice region is large, solitons are restricted in a hoof-like area. While fundamental solitons are always stable, dark vortices with unit charge can propagate stably under appropriate conditions. In addition, we reveal that the finite radial lattice plays an important role for the stabilization of highercharged vortex solitons. This is in sharp contrast to the higher-charged vortices in defocusing bulk media, where they unavoidably break into a set of single-charged vortices. Thus, we propose the first theoretical model which allows the existence of stable higher-charged dark vortex solitons. |
