Optical Hoovering on Plasmonic Rinks
Abstract
Excitation of surface waves on conducting materials provides a near resistance-free interface capable of a material glissade either by plasmon forces or optical beam tractors. Analogous to an ice hockey rink, as proof of principle plasmon assisted optical traction, or hoovering, of water drops on a gold surface is demonstrated. Variability in thresholds and movement is observed and can be explained by the presence of significant roughness, measured by SEM. The demonstration opens a path to directly integrate various optical and plasmonic glissade technologies. Ways of improving transport and potential applications spanning configurable microfluidics, antennas, diagnostics,sensing and active devices are discussed.
