Observation of vortex-ring "discrete" solitons in 2D photonic lattices
Nonlinear Guided Waves and Their Applications
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.doi:10.1364/nlgw.2004.ma3 fatcat:bk2iorohfjbavjqo63yfi6w53m
