Perfect vortices, whose ring profile is independent of the topological charge, play a key role in telecommunications and particle micro-manipulation.In Leisure Wear this work, we report the compact generation of a new kind of double-ring perfect vortices, called double-ring perfect vector beams, by exploiting dual-functional silicon metaoptics.In particular, we develop and test a new paradigm to generate those beams with the possibility of selecting different topological charges between the two rings.
The TV Power Cord generated beams are characterized through a filtering method, proving that the two rings have a vectorial nature with the same magnitude and either the same or different topological charges.Their unique properties suggest promising applications for optical tweezing and manipulation of low refractive-index particles, trapping of cold atoms, and high-capacity communications.
