Generalized ray optics and orbital angular momentum carrying beams
In classical optics theWolf function is the natural analogue of the quantumWigner function and like the latter itmay be negative in some regions.We discuss the implications this negativity has on the generalized ray interpretation of free-space paraxial wave evolution. Important examples include two classes of beams carrying optical orbital angularmomentum—Laguerre–Gaussian (LG) andBessel beams...
متن کاملMechanical Faraday effect for orbital angular momentum-carrying beams.
When linearly polarised light is transmitted through a spinning window, the plane of polarisation is rotated. This rotation arises through a phase change that is applied to the circularly polarised states corresponding to the spin angular momentum (SAM). Here we show an analogous effect for the orbital angular momentum (OAM), where a differential phase between the positive and negative modes (±...
متن کاملRapid generation of light beams carrying orbital angular momentum.
We report a technique for encoding both amplitude and phase variations onto a laser beam using a single digital micro-mirror device (DMD). Using this technique, we generate Laguerre-Gaussian and vortex orbital-angular-momentum (OAM) modes, along with modes in a set that is mutually unbiased with respect to the OAM basis. Additionally, we have demonstrated rapid switching among the generated mod...
متن کاملOrbital angular momentum of partially coherent beams.
The definition of the orbital angular momentum established for coherent beams is extended to partially coherent beams, expressed in terms of two elements of the beam matrix. This extension is justified by use of the Mercer expansion of partially coherent fields. General Gauss-Schell-model fields are considered, and the relation between the twist parameter and the orbital angular momentum is ana...
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...
