The on-site and off-site vortex-ring solitons of unity topological charge in a nonlinear photonic lattice were investigated. It was observed that the solitons exhibit stationary propagation, and the shapes of the vortices remain unchanged. In the presence of noise, the stability properties of these discrete vortex states were studied by simulating their propagation dynamics through the lattice. The results show that the both on-site and off-site vortex-ring solitons are stable in saturable nonlinear media.
