Zhigang Zheng,Zhigang Zheng,Cong-Long Yuan,Wei Hu,Hari Krishna Bisoyi,Ming-Jie Tang,Zhen Liu,Pei-Zhi Sun,Wei-Qiang Yang,Xiaoqian Wang,Dong Shen,Yannian Li,Fangfu Ye,Yan-qing Lu,Guoqiang Li,Quan Li +15 more
TL;DR: A facile way to realize designed micropatterning of a crystallographic direction of a soft, cubic liquid-crystal superstructure, exhibiting an alternate uniform and random orientation of the lattice crystallography direction enabled by a photoalignment technique is disclosed.
Journal ArticleDOI
Switchable Fresnel lens based on micropatterned alignment
TL;DR: The LCFZL, based on alternate twisted nematic and planar aligned regions, has been prepared by means of a two-step photo-alignment process and offers double the efficiency of existing FZLs.
