: Researchers said on Friday they have invented an antenna that
: captures visible light in much the same way that radio antennas
: capture radio waves.

: They say the device, using tiny carbon nanotubes, might serve as
: the basis for an optical television or for converting solar energy
: into electricity once properly developed.

: Yang Wang and colleagues at Boston College used carbon nanotubes,
: which are microscopic structures built out of carbon atoms.

: The tubes, pictured on the Internet at
: http://www.aip.org/png/2004/221.htm, are aligned randomly.

: The light excites miniature electrical currents, they write in the
: latest issue of the journal Applied Physics Letters.

: A visible-light antenna might work by receiving a television signal
: superimposed onto a laser beam sent down an optical fiber, the
: researchers said.

: 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.
