title: White-light photorefractive phase mask.
abstract: A volume photorefractive phase mask has been fabricated with incoherent white light from an incandescent source in LiNbO3:Fe self-defocusing photorefractive crystal for the first time, to our knowledge. It can guide and modulate a probe white light or a laser beam and can be used to transmit an incoherent dark image as the guided modes of the waveguides induced by white-light dark spatial solitons. This also proves the existence of photorefractive nonlinearity of white light.
