摘要:

近期发现的铁电向列相液晶,既具备向列相液晶流动性、可加工性和各向异性光学特性的功能组合,还拥有由相极性衍生的一系列惊人物理特性。其中,极高的二阶光学极化率值推动人们开发这类新型材料以用于非线性光子学应用。本研究表明,取向层的光刻图案化可用于构建极化图案。为此,我们利用挠曲电效应,设计出可从几何上定义极化方向的展曲结构。我们验证了周期性极化结构的构建,以及通过将展曲结构嵌入均匀背景来引导极化的可能性。本次验证的极化图案化能力,为设计基于铁电向列相的光子结构及其应用开辟了一条颇具前景的新路径。

英文摘要:

The recently discovered ferroelectric nematic liquids incorporate to the functional combination of fluidity, processability and anisotropic optical properties of nematic liquids, an astonishing range of physical properties derived from the phase polarity. Among them, the remarkably large values of second order optical susceptibility encourage to exploit these new materials for non-linear photonic applications. Here we show that photopatterning of the alignment layer can be used to structure polarization patterns. To do so, we take advantage of the flexoelectric effect and design splay structures that geometrically define the polarization direction. We demonstrate the creation of periodic polarization structures and the possibility of guiding polarization by embedding splay structures in uniform backgrounds. The demonstrated capabilities of polarization patterning, open a promising new route for the design of ferroelectric nematic based photonic structures and their exploitation.
