Size-invariant twisted optical modes for the efficient generation of higher-dimensional quantum states
Size-invariant twisted optical modes for the efficient generation of higher-dimensional quantum states
Optical vortex beams are profiled as helical wavefronts with a phase singularity carrying an orbital angular momentum (OAM) associated with their spatial distribution. The transverse intensity distribution of a conventional optical vortex has a strong dependence on the carried topological charge. However, perfect optical vortex (POV) beams have their transverse …
