Liquid Crystal Light Valves: a versatile platform for Nematicons

Gaetano Assanto, Armando Piccardi, Alessandro Alberucci, Stefania Residori, Umberto Bortolozzo


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.
