(a) Schematic of the experiment of Minovich et al. A gold grating deposited on a glass substrate is excited from below by a polarized 784 nm laser beam. A bent gold-coated fiber-optic tip with a 150 nm aperture is used to collect the light generated by surface plasmons (red peaks). (b) Image of Airy plasmons recorded with the fiber tip superimposed on a micrograph of the grating. (c) Numerical simulation of an Airy plasmon undergoing self-healing as it collides with a hole bored into the grating.
