Abstract
We report the first experimental observation of discrete solitons in an array of optically-induced waveguides. The waveguide arrays are induced in photorefractives by interfering pairs of plane waves, and the solitons form when the screening nonlinearity is employed. We demonstrate both in-phase and staggered bright solitons in 1-D and 2-D arrays. This constitutes the first experimental observation of 2D discrete solitons in any medium.
