Blending Beams of Light and Plasma in Real Time
A team based at the University of California, Berkeley,has liberated surface plasmon polaritons from the confines of fixed guiding nanostructures.
Examples of on-the-fly control of the plasmonic Airy beams, including switching the trajectories to different directions (a,b) and bypassing obstacles [the gray solid circles in (c)] along curved paths, where the left and right column correspond to numerical simulations and experimental demonstrations, respectively.
A team based at the University of California, Berkeley (U.S.A.), has liberated surface plasmon polaritons from the confines of fixed guiding nanostructures. The researchers have demonstrated how to control the trajectories of polaritons on a metal surface by coupling the polaritons to Airy beams (Opt. Lett. 36, 3191). This work confirms an earlier prediction made by a group at CREOL, the College of Optics and Photonics of University of Central Florida (Opt. Lett. 35, 2082).
