Dicke superradiance from a plasmonic nanocomposite slab

The Dicke superradiance from an optically thin nanocomposite slab represented by metal nanoparticles dispersed in a dielectric matrix is predicted and its theory developed first principles. It shown that the signal evolution determined eigenvalues of field susceptibility tensor for slab. excitation system pumping pulse different polarizations as well attenuated total reflection configuration considered. demonstrated relaxation rates are enhanced when surface plasmon polaritons excited at interface between substrate superstrate. These findings can pave way to extension optical techniques based on femtosecond time domain.
