A press release from Ecole Polytechnique Fédéralede:
A team of researchers from the Ecole Polytechnique Fédéralede Lausanne (EPFL) has successfully demonstrated, for the first time,that it is possible to control the speed of light – both slowing itdown and speeding it up – in an optical fiber, using off-the-shelfinstrumentation in normal environmental conditions. Their results, tobe published in the August 22 issue of Applied Physics Letters, couldhave implications that range from optical computing to the fiber-optictelecommunications industry.
