Electron vortices: Beams with orbital angular momentum [PDF]
Reviews of Modern Physics, 2017 The recent prediction and subsequent creation of electron vortex beams in a number of laboratories occurred after almost 20 years had elapsed since the recognition of the physical significance and potential for applications of the orbital angular momentum carried by optical vortex beams.

Orbital Angular Momentum Microlaser [PDF]
Conference on Lasers and Electro-Optics, 2016 Microlasers with a twist Structured light, in the form of helical wavefronts, provides an additional degree of freedom to encode information for optical communications. Creating light beams with the desired amount of optical angular momentum, or twist, has usually been achieved with bulk optic devices. Miao et al.

Spin and orbital angular momentum of coherent photons in a waveguide
Frontiers in Physics, 2023 Spin angular momentum of a photon corresponds to a polarisation degree of freedom of lights, and such that various polarisation properties are coming from macroscopic manifestation of quantum-mechanical properties of lights.
