本文以空间非局域双折射液晶为研究对象，建立了具有任意大双折射的各向异性介质中的空间光孤子和调制不稳定性理论。不对称的空间分布和多值功能的预测自定位光与走离角。结果适用于一般的自聚焦双折射介质，并适用于大角度转向的个人和多个自陷光束。
With reference to spatially nonlocal nematic liquid crystals, we develop a theory of optical spatial solitons and modulational instability in anisotropic media with arbitrarily large birefringence. Asymmetric spatial profiles and multivalued features are predicted for self-localized light versus walk-off angle. The results hold valid for generic self-focusing birefringent media and apply to large angle steering of individual and multiple self-trapped optical beams.
