Quantum and coherent signal transmission on a single-frequency channel via the electro-optic serrodyne technique. [PDF]

Sci Adv
Fiber-optical networks are well established to accommodate global data traffic via coherent information transmission. The next generation of telecommunications will require the integration of quantum information into fiber-optic networks, e.g., for ...

Time‐varying optical vortices enabled by time‐modulated metasurfaces

Nanophotonics, Volume 9, Issue 9, Page 2957-2976, February 2020., 2020
Abstract In this paper, generation of optical vortices with time‐varying orbital angular momentum (OAM) and topological charge is theoretically demonstrated based on time‐modulated metasurfaces with a linearly azimuthal frequency gradient. The topological charge of such dynamic structured light beams is shown to continuously and periodically change ...
