We demonstrate a novel phase-only modulation mode based on the pre-transitional effect of the antiferroelectric liquid crystal. 2π phase modulation without changing the polarization state of the incident light is achieved with a low field (1.8 V/μm). This phase modulation mode also shows an ultrafast response time (less than 300 μs) and a uniform optical texture with an easy fabrication process. This phase modulator can be applied to laser beam steering, virtual reality, and holograms, etc., in the future.
我们展示了一种基于反铁电液晶的预过渡效应的新型纯相位调制模式。在低场（1.8 V/μm）下实现了2π相位调制，同时不改变入射光的偏振态。这种相位调制模式还具有超快的响应时间（小于300μs）和均匀的光学纹理，且制造工艺简单。这种相位调制器未来可应用于激光束转向、虚拟现实和全息图等领域。
