Abstract
Dipole and vector solitons in a two-dimensional photorefractive optical lattice are demonstrated both experimentally and theoretically. Dipole solitons can be in-phase or out-of-phase in their lobe components, and they are trapped in two nearby lattice sites and stabilized by the lattice-induced waveguide. Vector solitons are realized by mutual trapping of two mutually incoherent beams in the same lattice site, although each beam alone experiences discrete diffraction.
