Dynamic generation of plasmonic bottle-beams with controlled shape

Research output: Contribution to journalArticlepeer-review

Abstract

We demonstrate the generation of plasmonic bottle-beams based on self-accelerating surface plasmons. These beams are excited from free-space beams through a special binary phase mask. The mask generates two mirror-imaged selfaccelerating surface plasmons, which form the plasmonic bottle-beam and a hot-spot at the point of convergence. The shape and area of the bottle-beams, together with the location of the hot-spot, are statically controlled by designing arbitrary convex trajectories for the two counter-accelerating beams and also are dynamically controlled by the illumination beam.
