BC physicists transmit visible light through miniature cable

CHESTNUT HILL, Mass., Jan 8 Physicists at Boston College have beamed visible light through a cable hundreds of times smaller than a human hair, an achievement they anticipate will lead to advances in solar power and optical computing.

The discovery, details of which appear in the Jan. 8 issue of the journal Applied Physics Letters, defies a key principle that holds that light cannot pass through a hole much smaller than its wavelength. In fact, the BC team forced visible light, which has a wavelength of between 380-750 nanometers, to travel down a cable whose diameter is smaller than even the low end of that range.

The researchers say their achievement opens the door to a wide array of new technologies, from high-efficiency, inexpensive solar cells to microscopic light-based switching devices for use in optical computing. The technology could even be used to help some blind people see, the physicists say.

The advance builds upon the researchers' earlier invention of a microscopic antenna that captures visible light in much the same way radio antennae capture radio waves a discovery they announced in 2004. This time, the BC physicists designed and fabricated a tiny version of the coaxial cable the Information Age workhorse that carries telephone and Internet service along with hundreds of television and radio channels into millions of homes and businesses around the world.

"Our coax works just like the one in your house, except now for visible light," says Jakub Rybczynski, a research scientist in the Boston College Physics Department and the lead author of the APL article.

Coaxial cables are typically made up of a core wire surrounded by a layer of insulation, which in turn is surrounded by another metal sheath. This structure encloses energy and lets the cable transmit electromagnetic signals with wavelengths much larger than the diameter of the cable itself.

With this design in mind, the physicists d
