Abstract: Autofocusing beams are powerful photonic tools for manipulating micro/nanoparticles. Here, we propose a special type of dislocated-superimposed swallowtail vortex beam (DSVB) and analyze its propagation properties and optical manipulating capability. By modulating the parameters of… read more here.
