IBM chip slows down the speed of light

By Derek Sooman on
IBM has developed a chip that slows down the speed of light. In a story that sounds more like something one would encounter in an episode of Star Trek The Next Generation, Big Blue has developed a chip that uses only a fraction of the energy and photonic silicon waveguide manages to achieve this great feat.

The chip works a bit like a speed camera. Light comes barrelling past at its normal 186,000 miles per second, jams on the anchors to one 1/300th of its normal speed as it passes by the holes and then speeds up again.

IBM says that the slower light pulses could carry data rapidly it could also be slowed further by applying an electric field to the waveguide.
