DARPA-Funded Device Adjusts the Speed of Light With the Twist of a Knob | Popular Science: "Built into a silicon chip, the small optical device has slowed the speed of light by a factor of 1,200 in the lab, in conditions that were previously unthinkable -- that is, under normal conditions. “Slow light,” as it’s known, has been produced before, but usually it requires special, lab-induced conditions – often at very low temperatures – that were too complicated for practical use. The UC Santa Cruz team designed their device to work at room temperature and to be produceable in market quantities."
