Because of their non-diffraction and freely acceleration during propagation, finite energy Airy beams are interesting for application such as optical manipulation, plasma channel generation and optical vortex generation. Especially interesting are tunable/switchable Airy beams, in which the Airy beam tuning by electric field, temperature or optical intensity can be realized. Here we experimentally demonstrate polarization-independent, electrically tunable/switchable Airy beam based on polymer-stabilized blue phase liquid crystals with wide working temperature range and fast response time through a structure called vertical field driven mode.
由于有限能量艾里光束在传播过程中具有无衍射和自由加速的特性,它们在诸如光学操控、等离子体通道产生和光学涡旋产生等应用中很有吸引力。特别有趣的是可调谐/可切换艾里光束,其中可以实现通过电场、温度或光强度对艾里光束进行调谐。在此,我们通过一种称为垂直场驱动模式的结构,基于具有宽工作温度范围和快速响应时间的聚合物稳定蓝相液晶,实验证明了偏振无关、电可调谐/可切换的艾里光束。
