Generation and Near-Field Imaging of Airy Surface Plasmons

Minovich, Aliaksandr; Klein, Angela E; Janunts, Norik; Pertsch, Thomas; Neshev, Dragomir; Kivshar, Yuri

Description

We demonstrate experimentally the generation and near-field imaging of nondiffracting surface waves, plasmonic Airy beams, propagating on the surface of a gold metal film. The Airy plasmons are excited by an engineered nanoscale phase grating, and demonstrate significant beam bending over their propagation. We show that the observed Airy plasmons exhibit self-healing properties, suggesting novel applications in plasmonic circuitry and surface optical manipulation.
