    "abstract": "We demonstrate second-band bright vortex-array solitons in photonic lattices.\nThis constitutes the first experimental observation of higher-band solitons in\nany 2D periodic system. These solitons possess complex intensity and phase\nstructures, yet they can be excited by a simple highly-localized vortex-ring\nbeam. Finally, we show that the linear diffraction of such beams exhibits\npreferential transport along the lattice axes.",
