An interface between two periodic 1D arrays with self-focusing Kerr nonlinearities is shown experimentally to support strikingly different families of surface solitons due to differences in surface potential near the boundary.
We have investigated the power threshold of discrete Kerr surface solitons at the interface between discrete and continuous 1D AlGaAs medium. Distinct thresholds were measured for interface solitons localized at different sites from the interface.
We provide an overview of recent theoretical and experimental results in the area of surface lattice solitons. The observation of these waves in Kerr and quadratic nonlinear periodic structures is discussed
We report the first observation of discrete optical surface solitons at the interface between a nonlinear self-focusing waveguide lattice and a continuous medium. The effect of power on localization process of these states is investigated.
We observed, for the first time, the breakup of a wide high intensity beam due to modulational instability in the normal diffraction region of a discrete optical system and its absence in the anomalous regime.
