Spin-to-orbital angular momentum conversion in dielectric metasurfaces: erratum.
We would like to clarify our paper [Opt. Express25, 377 (2017)] abstract sentence "These beams carry orbital angular momentum proportional to the number of intertwined helices constituting the wavefront."
متن کاملAcoustic rotational manipulation using orbital angular momentum transfer.
We report on the first quantitative test of acoustic orbital angular momentum transfer to a sound absorbing object immersed in a viscous liquid. This is done by realizing an original experiment that is to spin a millimeter-size target disk using an ultrasonic vortex beam. We demonstrate the balance between the acoustic radiation torque calculated from the Brillouin stress tensor and the viscous...
متن کاملNanostructured optical elements for manipulation of orbital angular momentum
Applications of glass nanostructuring for manipulation of orbital angular momentum are reviewed. The phase control is implemented via the combination of form birefringence and Pancharatnam-Berry phase.
متن کاملPlasmonic orbital angular momentum manipulation through light control
Plasmonic vortices (PV) excited by a highly focused radially polarized optical vortex (RPOV) beam on a metal surface are investigated experimentally and theoretically. The proposed method reveals a direct phase singularity and orbital angular momentum (OAM) transfer from an incident structured beam to its counterpart in surface plasmon with dynamic, reconfigurable and high-efficiency advantages...
متن کاملOrbital angular momentum spectrum of entangled two-photon states
We implement an interferometric method to measure the orbital angular momentum (OAM) spectrum of photon pairs generated by spontaneous parametric down-conversion. In contrast to previous experiments, which were all limited by the modal capacity of the detection system, our method operates on the entire down-conversion cone and reveals the complete distribution of the generated OAM. In this geom...
