    Figures & Tables(7)
    (a)Sructure of the liquid crystal cell;(b)Sketch of the internal electrode pattern.
    Simulation of the liquid crystal molecular director field distribution in a liquid crystal cell with a comb electrode at different voltages.(a)V=0 V;(b)V=1 V;(c)V=3 V;(d)V=5 V. The lines in the diagram represent the potential lines and the colour bars correspond to the height of the potential.
    Experimental optical path
    Variation of the beam at different incident positions at 3 V,with input optical power P=1.05 mW.(a)d=42 μm;(b)d=144 μm;(c)d=268 μm;(d)d=163 μm;(e)d=60 μm;(f)d=242 μm.
    Combination of deflection by nematicon pairs at different incidence positions.(a)V=0 V,the light beam propagates straight.(b~f)V=4 V,the two light beams undergo deflection at different incidence positions.
    Combination of deflection by nematicons pairs at different incidence positions under tilted incidence,with assisted voltage V=4 V,and the input optical power of the upper and lower beams are P1=0.95 mW,P1=0.74 mW.(a)Incidence position of the nematicon pairs is in the ITO etching region;(b)Incidence position of the nematicon pairs is on both sides of the dividing line between the ITO etching region and the ITO region.
    Deflection of the nematicon pairs is modulated by voltage.(a)(c)V=0 V;(b)(d)V=3.5 V.
