Swiss researchers have successfully demonstrated for the first time that it is possible to control the speed of light in an optical fiber.

A team of researchers from the Ecole Polytechnique Federale in Lausanne, Switzerland, said the findings, published in Applied Physics Letters, could have implications ranging from optical computing to the fiber-optic telecommunications industry.

The researchers were able to slow light down and speed it up as well.

The phenomenon could have profound technological consequences in controlling the speed of light in a simple optical fiber, according Luc Thevenaz and his fellow researchers.

This has the enormous advantage of being a simple, inexpensive procedure that works at any wavelength, notably at wavelengths used in telecommunications, said Thevenaz.
