Researchers Slow Light to a Crawl in Liquid Crystal Matrix
Washington DC (SPX) Aug 14, 2013
Light traveling in a vacuum is the Universe's ultimate speed demon, racing along at approximately 300,000 kilometers per second. Now scientists have found an effective new way to put a speed bump in light's path. Reported in The Optical Society's (OSA) open-access journal Optics Express, researchers from France and China embedded dye molecules in a liquid crystal matrix to throttle the group velocity of light back to less than one billionth of its top speed. The team says the ability to slow light ... read more
