a, Side view of the 3D iso-intensity profile of a photonic toroidal vortex. The colours denote the rotating spatiotemporal spiral phase (\({\varPhi }_{{{r}_ \bot },\,{t}}\)). The topological charge of the spiral phase is 1. The direction of local OAM density (jOAM) is marked with arrows. b, Front view of the iso-intensity profile of a photonic toroidal vortex.
