Název v původním jazyce

Spin-locked scattering forces in the near field of high index particles

Popis výsledku v původním jazyce

The ever-growing field of microfluidics is currently in the need of a variety of controllable components to perform operations inside microchambers. Brand-new nanophotonic approaches can significantly enhance existing capabilities via light-matter interactions. We propose a novel concept featuring dual on-chip functionality: boosted optically-driven diffusion and sorting. Recently, well-designed high-index nanoantennae have been shown to mediate strong spin-orbit coupling from a laser beam, producing subwavelength optical nanovortices that drive spiral motion of absorbing nanoparticles (NPs) by means of scattering forces. In this work, we exploit further this idea and take the first step towards the realization of directional fluid navigation, investigating near field interactions of two optical nanovortices generated by a dielectric dimer structure.
