Toward Applications of Slow Light Technology

Enrique Parra and John R. Lowell

Scientists working for the Defense Advanced Research Projects Agency (DARPA) are making progress toward the development of robust, integrated devices that can slow, store and process light pulses. Their research will have a far-reaching impact on high-speed optical processing, telecommunications networks and quantum information science.


figureAll-optical data processing operations enabled by slow light. All-optical processing relies on the ability to store, switch and time delay light pulses to create and control data buffers, logic switches and tunable signal delays.

Information processing networks, such as those used in telecommunications and high-speed radio-frequency signal processing, use a physical architecture based on high-speed electrical circuits for data routing and optical fibers for transporting data traffic.
