Abstract:We illustrate the generation and control of optical spatial solitary waves (nematicons) in liquid crystal light valves with nematic liquid crystals and a photoconductive layer. The latter allows to all-optically varying the birefringent walk-off and the extraordinary-wave refractive index, hence, the trajectory of a nematicon propagating in the thickness of the valve.
