"Light, Metal and Molecules"
Surface plasmons have generated considerable interest in recent years for their potential applications from sensing to photonic devices. In this regard, subwavelength holes in optically thick metal films which give rise to resonant transmission due to the involvement of surface plasmons offer many interesting possibilities [1]. Here we will focus on the exploration of surface plasmon -- molecule interactions in hole arrays and in single apertures. Results show that such aperture structures can, among other things, give rise to enhanced absorption, enhanced emission, strong coupling and index switching (e.g. ref. 2-4). Such results will be presented together with examples of ultra-fast caracterisation of the surface plasmon -- molecule hybdrid states. Finally, the implications for chemistry, from spectroscopy to modifying molecular state properties, will be discussed.
