Near-Field Evolution of Optical Vortices and Their Spatial Ordering behind a Fork-Shaped Grating
Fork-shaped gratings are periodic structures containing a spatial dislocation known to be used for the production of optical vortices in a far field. Spatial overlapping of diffraction orders in a near field results in complex spatial evolution of optical vortices. In this paper, we report the resul...
