AbstractLight can be tailored to carry angular momentum well beyond the restriction of its two spin states, left- and right-circularly polarized light, by imbuing it with orbital angular momentum (OAM). OAM is controlled by imparting finer and finer azimuthal phase gradients, twisting the wavefront ever tighter in one of two helicities, clockwise or anticlockwise.
