Abstract

Conspicuous efforts have been devoted to exploit spatial solitons for signal processing. In nematic liquid crystals steering of spatial solitons or nematicons has been reported in planar cells.^1-2 In this Communication, we demonstrate excitation and tunable propagation of spatial solitons in photoconductive Light Valves filled with nematic Liquid Crystals (LCLV).^3-4 We show that nematicons can be effectively launched and deviated in LCLV, combining self-guidance with parallel nonlinear optical processing.
