Abstract
Exploiting electro-optic effects in liquid crystals, we achieved real-time control of the retardation of liquid- crystal-based -plates through an externally applied voltage. The newly conceived electro-optic -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.
