    Abstract

    We provide an overview of experimental studies on partially coherent spatial solitons in photorefractive materials, including the first experimental demonstration of bright and dark incoherent solitons, incoherent vortex solitons, Y-junction dark solitons and anti-dark solitons, and pixel-like incoherent soliton arrays. These solitons are created with partially spatially incoherent light beams by using the non-instantaneous photorefractive screening nonlinearity. Experimental results on waveguides induced by incoherent solitons are also presented and their potential applications for soliton-driven photonics are discussed. In particular, these experiments introduce the possibility of controlling high-power laser beams with low-power incoherent light sources in waveguide arrays as well as in planar, circular and beam-splitting waveguides optically induced in bulk photorefractive materials.
