We present an experimental and theoretical investigation of the optical diffractive properties of electrically tuneable optical transmission gratings assembled as stacks of periodic slices from a conventional nematic liquid crystal (E7) and a standard photoresist polymer (SU-8). The external electri ...

Polymer-stabilized cholesteric liquid crystals (PSCLCs) have emerged as promising candidates for one-dimensional photonic lattices that enable precise tuning of the photonic band gap (PBG). This work systematically investigates the effect of polymer concentrations on the AC electric field-induced tu ...

Fractional Talbot lithography for predesigned large-area liquid-crystal alignment
Zhichao Ji, Zenghua Gan, Yu Wang, Zhijian Liu, Donghao Yang, Yujie Fan, Wenhua Li, Irena Drevenšek Olenik, Yigang Li, Xinzheng Zhang
Izvirni znanstveni članek
Oznake: tekoči kristali;litografija;liquid crystals;lithography;
To address the increasing demands for cost-effective, large-area, and precisely patterned alignment of liquid crystals, a fractional Talbot lithography alignment technique was proposed. A light intensity distribution with a double spatial frequency of a photomask could be achieved based on the fract ...
