On a wire or in a fiber, a wave is a wave

In an experiment modeled on the classic "Young's double slit experiment" researchers have powerfully reinforced the understanding that surface plasmon polaritons move as waves and follow analogous rules.

Modern redux of classic experiment illuminates nanoscience of 'plasmonics'

The science of plasmonics describes how metals can essentially transmit and manipulate light waves at length scales much smaller than their wavelengths. Now, by redoing a classic optics experiment with plasmonics, engineers have made key insights into the nature and the practical limits of this up-and-coming nanoscale information technology.
