Generation of Propagation-Dependent OAM Self-Torque with Chirped Spiral Gratings
The application of non-uniform spiral gratings to control the structure, topological parameters and propagation of orbital angular momentum (OAM) beams was studied experimentally with coherent near-infrared light. Adapted digital spiral grating structures were programmed into the phase map of a high...
