摘要

Nanoscale materials absorb, propagate, and dissipate energy very differently than their bulk counterparts. Furthermore, hybrid nanostructures consisting of molecular and plasmonic materials with strongly coupled electronic states can produce new optical states and decay pathways that provide additional handles with which to externally control energy flow in complex nanostructured systems. In this talk, we discuss our recent studies of electromagnetic coupling and associated temporal dynamics of molecular excitations with plasmonic resonances supported by either localized or extended planar geometries. Recent experimental results and theoretical analysis for observing and controlling coherences between molecular excitations and plasmonic polarizations are shown. Advances will explore new directions in ultrafast manipulation of energy dissipation processes in hybrid plasmonic structures, as well as ultrafast addressing and switching in plasmonics-based circuit architectures. Also discussed are recent synthetic advances in the creation of hybrid materials. Ultimately, these studies may impact a range of next-generation optical materials and devices, of relevance to new energy conversion materials, nanoscale photocatalysis, or plasmon-enhanced sensors.
