Continuous variable entanglement and squeezing of orbital angular momentum states.
We report the first experimental characterization of the first-order continuous variable orbital angular momentum states. Using a spatially nondegenerate optical parametric oscillator (OPO) we produce quadrature entanglement between the two first-order Laguerre-Gauss modes. The family of orbital angular momentum modes is mapped on an orbital Poincaré sphere, where the mode's position on the sph...
متن کاملOptical orbital angular momentum.
We present a brief introduction to the orbital angular momentum of light, the subject of our theme issue and, in particular, to the developments in the 13 years following the founding paper by Allen et al. (Allen et al. 1992 Phys. Rev. A 45, 8185 (doi:10.1103/PhysRevA.45.8185)). The papers by our invited authors serve to bring the field up to date and suggest where developments may take us next...
متن کاملUndulator Photon Beams with Orbital Angular Momentum
Abstract Photons carrying an orbital angular momentum (OAM) are present in the off-axis radiation of higher harmonics of helical undulators. Usually, the purity and visibility of OAM carrying photons is blurred by the electron beam emittance. However, high brightness OAM beams are expected in Ultimate Storage Rings (USRs) and FELs, and they may trigger a new class of experiments utilizing the v...
متن کاملMillimetre Wave with Rotational Orbital Angular Momentum
Orbital angular momentum (OAM) has been widely studied in fibre and short-range communications. The implementation of millimetre waves with OAM is expected to increase the communication capacity. Most experiments demonstrate the distinction of OAM modes by receiving all of the energy in the surface vertical to the radiation axis in space. However, the reception of OAM is difficult in free space...
