Abstract
Recent research on manipulating the speed of light has established the possibility of bringing down the speed of light to a value that can be challenged by a humble bullock cart. The processes that influence the speed of light in natural and artificial materials have been investigated in depth, leading to the design of specific techniques to slow down and even store light in appropriate medium at room temperature. We introduce here the basic science of slow-light propagation in materials and artificial structures such as photonic crystals and highlight the important milestones in research on this fascinating frontier. © 2013 Indian Academy of Sciences.
