Abstract
We introduce novel classes of optical vector solitons that consist of incoh erently coupled self-trapped "necklace" beams carrying zero, integer, and e ven fractional angular momentum. Because of the stabilizing mutual attracti on between the components, such stationary localized structures exhibit qua sistable propagation for much larger distances than the corresponding scala r vortex solitons and expanding scalar necklace beams.
