我们展示了一个快速切换（亚毫秒）相位光栅的基础上，聚合物稳定的短间距手性液晶，电寻址使用面内电场。短间距和聚合物稳定的组合使得衍射图案能够在600 μ s内可逆地“开”和“关”。结果呈现在远场衍射图案上，沿着衍射级的强度作为所施加的电场和响应时间的函数。(C)2011年美国物理学会。[doi：10.1063/1.3670041]
We demonstrate a fast-switching (sub-millisecond) phase grating based upon a polymer stabilized short-pitch chiral nematic liquid crystal that is electrically addressed using in-plane electric fields. The combination of the short-pitch and the polymer stabilization enables the diffraction pattern to be switched "on" and "off" reversibly in 600 mu s. Results are presented on the far-field diffraction pattern along with the intensity of the diffraction orders as a function of the applied electric field and the response times.
