Yang Wang and colleagues at Boston College have invented an antenna that captures visible light in much the same way that radio antennas capture radio waves.
The researchers used tiny carbon nanotubes, which are microscopic structures built out of carbon atoms.
This technology may improve the efficiency and quality of television signals.
Or it could be used as the basis of an efficient solar energy device that turns incoming light into an electrical charge to be stored in a capacitor, they said.
