Orbit–Orbit Interaction in Spatiotemporal Optical Vortex Open
While spin–orbit interaction has been extensively studied, few investigations have reported on the interaction between orbital angular momenta (OAMs). In this work, we study a new type of orbit–orbit coupling between the longitudinal OAM a…

Highly localized continuous wave optical vortex with controllable orbital angular momentum orientation and topological charge Open
We report an approach to simultaneously control orbital angular momentum (OAM) orientation and topological charge in highly localized optical vortices by employing a 4π focusing system. The required continuous wave illumination field in th…
