Caption: This figure shows how to excite and dynamically control plasmonic Airy beams on a thin gold film. Through a grating coupler [see Inset (a)], an Airy beam in free space [see Inset (b)] generated with a computer addressed spatial light modulator (SLM) is directly coupled into surface plasmon polaritons, which is monitored via leakage radiation microscopy. The on-the-fly adjustment of the created plasmonic Airy beam is achieved by displaying an animation of specially designed patterns in SLM.
