D. Kip et al., Transmission of images through highly nonlinear media by gradient-index lenses formed by incoherent solitons, OPTICS LETT, 26(8), 2001, pp. 524-526
Sire experimentally demonstrate image transmission through a noninstantaneo
us self-focusing medium. partially spatially incoherent soliton is used to
form a multimode waveguide in a photorefractive crystal, and the modes of t
hat waveguide are used to transmit an incoherent image through this nonline
ar medium. (C) 2001 Optical Society of America.
