Tiny holes offer surprising insights Researchers from Berlin and Seoul store light in plasmonic crystals Light can creep through tiny holes in a metal plate, even if those holes are smaller in diameter than the wavelength of light. What`s more, the light is stored for a short period of time on the metal surface, as if the metal were a photonic crystal. The controlled interaction of light with such metal structures could pave the way to unique methods for nanosensing or nanoscale information transfer, write Claus Ropers and colleagues in the forthcoming issue of Physical Review Letters ("Femtosecond light transmission and subradiant damping in plasmonic crystals").
