The silicon absorbed 99.4 per cent of near-infrared light with a wavelength of 998.5 nanometres, turning it into heat. "Theory and experiment matched very well," says Stone. "We couldn't have expected to do any better."
Future computers may use light to transmit signals efficiently between their chip processors. Anti-lasers could be used to modulate the intensity of that light, or to convert light signals into electrical form for on-chip processing, the researchers say.
Sounds like my ideal Christmas morning.
