Uncovering low-frequency vibrations in surface-enhanced Raman of organic molecules
Alexandra Boehmke, Roberto A Boto, Eoin Elliot +7
Accessing the terahertz (THz) spectral domain through surface-enhanced Raman spectroscopy (SERS) is challenging and opens up the study of low-frequency molecular and electronic exc…
Boosting Optical Nanocavity Coupling by Retardation Matching to Dark Modes
Rohit Chikkaraddy, Junyang Huang, Dean Kos +5
Plasmonic nano-antennas can focus light to nanometre length-scales providing intense field enhancements. For the tightest optical confinements (0.5-5 nm) achieved in plasmonic gaps…
Giant optomechanical spring effect in plasmonic nano- and picocavities probed by surface-enhanced Raman scattering
Lukas A. Jakob, William M. Deacon, Yuan Zhang +8
Molecular vibrations couple to visible light only weakly, have small mutual interactions, and hence are often ignored for non-linear optics. Here we show the extreme confinement pr…
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…
Strong-coupling of WSe2 in ultra-compact plasmonic nanocavities at room temperature
Marie-Elena Kleemann, Rohit Chikkaraddy, Evgeny M. Alexeev +9
Strong-coupling of monolayer metal dichalcogenide semiconductors with light offers encouraging prospects for realistic exciton devices at room temperature. However, the nature of t…
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…
