Orbital angular momentum of structured vortex beams induced by intensity singularity

Orbital angular momentum of structured vortex beams induced by intensity singularity

A new category of optical orbital angular momentum (OAM) associated with intensity singularity independent of phase singularity is predicted, and a kind of structured vortex beams (VBs) with arbitrary transverse shapes is demonstrated. A universal inverse-designed caustic scheme is developed for gen...
