Bruno Piccirillo, Vincenzo D'Ambrosio, Sergei Slussarenko, Lorenzo Marrucci, Enrico Santamato

摘要:

利用液晶的电光效应,我们通过外加电压实现了对液晶基$q$板延迟的实时控制。新构思的电光$q$板可以作为光子自旋到轨道角动量的电驱动转换器来操作,使得输出光子的轨道角动量概率在毫秒的时间尺度上变化。

英文摘要:

Exploiting electro-optic effects in liquid crystals, we achieved real-time control of the retardation of liquid- crystal-based $q$-plates through an externally applied voltage. The newly conceived electro-optic $q$-plates can be operated as electrically driven converters of photon spin into orbital angular momentum, enabling a variation of the orbital angular momentum probabilities of the output photons over a time scale of milliseconds.
