title: Observation of vortex-ring "discrete" solitons in 2D photonic lattices.
abstract: We present the experimental observation of both on-site and off-site vortex-ring solitons of unity topological charge in a nonlinear photonic lattice, along with a theoretical study of their propagation dynamics and stability.
