Trapped rainbow: New technique to slow down, stop and capture light

The technique would allow the use of light rather than electrons to store memory in devices such as computers, enabling an increase in operating capacity of 1,000% by using light‚??s broad spectrum rather than single electrons. Slow light could also be used to increase the speed of optical networks, such as the Internet.
