摘要

向列相液晶是一种研究空间光孤子的绝好的非局域非线性介质。为了对向列相液晶中空间光孤子的偏转进行灵活的调制，设计了具有梳状电极结构的液晶盒。对这种定制电极结构的液晶盒施加电场可以实现向列液晶在周期阵列内的调制，从而实现了向列子和向列子对的可控偏转。在液晶分子的不同取向区域，入射激光束形成的向列子可以产生不同角度的偏转。当光束入射到定制电极宽度为910 μm的液晶盒中，通过改变光束的入射位置可以实现单光束约60°范围内的偏转。双光束入射到不同的位置可以形成多种偏转组合形式。改变光束的入射角度，可以观察到向列子对在界面处的非线性全反射。此外，将定制条纹电极的宽度更改为300 μm后，向列子对可以实现平行传输到相互会聚或发散之间的切换。这些关于向列子偏转的调控方法可以在全光电路和光通信中发挥重要作用。

Abstract

The nematic liquid crystal is an excellent non-local nonlinear medium for the study of spatial optical solitons. In order to achieve a flexible modulation of the deflection of spatial optical solitons in nematic liquid crystals， the structure of a liquid crystal cell with a comb-shaped electrode structure is designed. Applying an electric field to the liquid crystal cell with customized electrode structure enables modulation of the nematic liquid crystal within the periodic array， thus enabling controlled deflection of the nematicon and nematicon pairs. The incident laser beam can be deflected at different angles in different orientation ranges. When the beam is incident in a liquid crystal cell with a customized electrode width of 910 μm， the deflection of the beam can be adjusted within a range of 60° by changing the incident position. Various combinations of deflections can be formed by two laser beams incident at different positions. By varying the angle of incidence， a non-linear total reflection of the nematicon pairs at the interface can be observed. Furthermore， the width of the customized stripe electrode is changed to 300 μm， the nematicon pairs achieves a switch parallel transmission to mutual convergence and divergence. These methods of modulation nematicons deflection can play an important role in all optical circuit and optical communications.
