Active plasmonics

Abstract: 
Metal nanostructures supporting surface plasmon polaritons SPPs) carry significant potential for guiding and manipulating light on the nanoscale. SPPs are spatially confined electromagnetic field modes at a metal-dielectric interface generating ultrashort and intense near-field optical forces, which can potentially be used to enhance and control the optical response of quantum emitters, the key components of the diverse, contemporary photonics applications. Investigations of SPP-quantum emitter interactions have led to the emerging and exciting field of active plasmonics, dealing with ultrafast all-optical control of SPPs on the nanoscale. In this talk, some aspects of the fundamental physical mechanism in active plasmonics, namely the SPP-quantum emitter dipole coupling will be explored.
