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.
