Nonlinear THz resoponse of graphene plasmonic structures

Winnerl, S.; Jadidi, M. M.; Chin, M.; Seidl, A.; Schneider, H.; Helm, M.; Drew, H. D.; Murphey, T. E.; Mittendorff, M.
Ribbons and discs based on doped graphene feature strong tunable plasmonic resonances. We show that excitation with THz radiation results in strong changes of transmission, even at moderate pump fluences. The response is due to a broadening and redshift for the plasmonic absorption line as charge carriers are heated. The response time is determined by the cooling of carriers, which is of the order of 10 ps.
