Team invents non-metallic metamaterial that enables them to 'compress' and contain light
The invention of fibre optics revolutionized the way we share information, allowing us to transmit data at volumes and speeds we'd only previously dreamed of.
Now, electrical engineering researchers at the University of Alberta in Edmonton, Alberta, Canada are breaking another barrier, designing nano-optical cables small enough to replace the copper wiring on computer chips.
This could result in radical increases in computing speeds and reduced energy use by electronic devices.
"We're already transmitting data from continent to continent using fibre optics, but the killer application is using this inside chips for interconnects—that is the Holy Grail," says Zubin Jacob, an electrical engineering professor leading the research. "What we've done is come up with a fundamentally new way of confining light to the nano scale."
At present, the diameter of fibre optic cables is limited to about 1/1000th of a millimetre. Cables designed by graduate student Saman Jahani and Jacob are 10 times smaller—small enough to replace copper wiring still used on computer chips. (Put into perspective, a dime is about 1 mm thick.)
Jahani and Jacob have invented a new, non-metallic metamaterial that enables them to "compress" and contain light waves in smaller cables without creating heat, slowing the signal or losing data. Their findings will be published in Optica (Aug. 20), The Optical Society's (OSA) new high-impact photonics journal. The article is available online.
The team's research is funded by the Natural Sciences and Engineering Research Council of Canada and the Helmholtz-Alberta Initiative.

Waveguides are widely used for filtering, confining, guiding, coupling or splitting beams of visible light. However, creating waveguides that could do the same for X-rays has posed tremendous challenges in fabrication, so they are still only in an early stage of development.
