Oral Communication

Besides circular polarization, which encodes a Spin Angular Momentum (SAM), Laguerre-Gaussian beams also carry Orbital Angular Momentum (OAM), amounting to ℓℏ per photon, due to an azimuthal dependence in the electric-field phase of the form exp(iℓ𝜑) [1]. As the OAM index ℓ defines a set of orthogonal modes, OAM beams found application in high-bandwidth optical data transfer [2]; their ability...
