Abstract :
The properties of slow-light optical delay lines, with low group velocity induced by electromagnetically induced transparency, population oscillations and photonic crystal filter structures, are analysed. It is shown that there are fundamental limitations on the delay-bandwidth product and the maximum storage density of data in slow-light devices.
