Abstract :
We study for the first time the ultrafast optical nonlinearities of hybrid, metal-J-aggregate nanostructures using angle-resolved pump-probe-spectroscopy. Our results demonstrate that the strong coupling between surface plasmon polaritons and excitons drastically alters the polariton dynamics.
