The field of plasmonics—in which surface plasmon resonances of metals are used
to manipulate light at the sub-wavelength scale—is transforming our understanding
of nanophotonics and integrated optics. Now, researchers are harnessing the power
of plasmonics, paving the way to wavefront engineering of laser beams.
