Nano-Scale Optical Co-Axial Cables Announced

Posted by ScuttleMonkey on from the hairy-logic dept.

toybuilder writes "Reuters reports that scientists have published their work on nano-scale optical coax in the most recent issue of Applied Physics Letters. The coax cable is only about 300nm wide, and is able to transmit optical signals using a carbon center conductor, transmitting light at about 90% the speed of light."

    Light always travels at 100% of the speed of light. However, in this cable, light travels at about 90% of the speed of light in a vacuum.

    Hardly -- the statement is a little stupid because it doesn't mention the constant c nor "the speed of light in a vacuum", it simply says "the speed of light" -- most people will recognize the error, but it's still an error.
