摘要

手性液晶材料可以自组织成由弯曲胆甾螺旋和空间有序缺陷组成的多层调制结构。我们成功地制备了具有显著结构和光子特性的周期性二维胆甾畴。它们是由于几何挫折而形成的。在透射和反射中发现并研究了图像对光偏振和观测几何形状的非平凡依赖的复杂光学模式。所获得的二维有序共焦域的光子结构及其光学性质对理论和实验都是一个挑战。

Photonics of Two-Dimensional Structures Formed by Cholesteric Liquid Crystals

Chiral liquid crystal materials can self-organize into modulated structures with multilevel arrangement formed by curved cholesteric helixes and spatially ordered defects. We managed to prepare periodic two-dimensional cholesteric domains with remarkable structure and photonic properties. They are formed due to geometrical frustration. Complex optical patterns with non-trivial dependence of the images on light polarization and on observation geometry were found and investigated in transmission and reflection. The obtained photonic structures of two-dimensional ordered confocal domains and their optical properties are a challenge both for theory and experiment.
