We analyze the angular steering of self-confined light beams, i.e., spatial solitons, in nematic liquid crystals exploiting both their electro-optic response and reorientational nonlinearity. A bias-induced interface is obtained with comb electrodes in a planar cell, applying two distinct voltages to control the spatial distribution of the optic axis. The configuration allows spatial solitons to propagate in a plane and maximize their deflection via refraction and total internal reflection, with an overall deflection of 70° in standard E7.
我们分析了在向列相液晶中利用电光响应和重取向非线性实现自限制光束（即空间孤子）的角转向。在平面池中采用梳状电极获得偏压诱导界面，施加两个不同的电压以控制光轴的空间分布。该配置允许空间孤子在一个平面内传播，并通过折射和全内反射使它们的偏转最大化，在标准 E7 中整体偏转角为 70°。
