Mapping nanoscale hotspots with single-molecule emitters assembled into plasmonic nanocavities using DNA origami
Rohit Chikkaraddy, V. A. Turek, Nuttawut Kongsuwan +8
Fabricating nanocavities in which optically-active single quantum emitters are precisely positioned, is crucial for building nanophotonic devices. Here we show that self-assembly b…
Suppressed Quenching and Strong Coupling of Purcell-Enhanced Single-Molecule Emission in Plasmonic Nanocavities
Nuttawut Kongsuwan, Angela Demetriadou, Rohit Chikkaraddy +5
An emitter in the vicinity of a metal nanostructure is quenched by its decay through non-radiative channels, leading to the belief in a zone of inactivity for emitters placed withi…
Anomalous spectral shift of near- and far-field plasmonic resonances in nano-gaps
Anna Lombardi, Angela Demetriadou, Lee Weller +5
The near-field and far-field spectral response of plasmonic systems are often assumed to be identical, due to the lack of methods that can directly compare and correlate both respo…
Generalized circuit model for coupled plasmonic systems
Felix Benz, Bart de Nijs, Christos Tserkezis +6
We develop an analytic circuit model for coupled plasmonic dimers separated by small gaps that provides a complete account of the optical resonance wavelength. Using a suitable equ…
