These orbital angular momentum (OAM) states have the potential to vastly increase bandwidth, but they are difficult to handle. Some recent research, however, suggests that we might well be using ...

Light carries both spin and orbital angular momentum. These dynamical properties are determined by the polarization and spatial degrees of freedom of light. ... (Berry) phases 75,76.
