Nanowire chip channels light

  October 13/20, 2008
Embed the ends of silver nanowires into the side of a plastic waveguide and you have a building block for chips that control thousands of light signals.

A prototype optical chip channels light into and out of silver nanowires, which can transmit light in a space smaller than the light's wavelength. This opens the way for densely packed optical chips that will be able to support higher capacity telecommunications networks.
