    "abstract": "We show that an azimuthally-periodically-modulated bright ring \"necklace\"\nbeam can self-trap in self-focusing Kerr media and can exhibit stable\npropagation for very large distances. These are the first bright (2+1) D beams\nto exhibit stable self-trapping in a system described by the cubic (2+1) D\nNonlinear Schrodinger Equation (NLSE).",
