Observation Of Two-Dimensional Discrete Solitons In Optically-Induced Nonlinear Photonic Lattices

The first experimetal observation of 2D optial discrete solitons in nonlinear photonic lattices was reported. As such, optical induction technique was used to create 2D nonliear photonic lattices in a photorefractive crystal. In these lattices, the diffraction and the two families of discrete self-trapped wavepackets were studied: the in-phase and the staggered 2D lattice solitons
