The laws of physics dictate that traditional lenses can't focus light onto a spot narrower than half the wavelength of the light. However, in a move which promises to increase computation speed, converting the light into waves called plasmons can get around this limitation.

Plasmonic lithography, which uses plasmon-generated radiation to carve physical features into a substrate, promises to revolutionize optical storage and computing, enabling ultradense DVDs and powerful microprocessors.

Now, researchers at the University of California, Berkeley, have surmounted the biggest obstacle to plasmonic lithography by building a prototype that brings a plasmonic lens very close to the substrate.
