Anti-Stokes Photoluminescence in Monolayer WSe Activated by Plasmonic Cavities through Resonant Excitation of Dark Excitons

Niclas S. Mueller, Rakesh Arul, Ashley P. Saunders +9

Anti-Stokes photoluminescence (PL) is light emission at a higher photon energy than the excitation, with applications in optical cooling, bioimaging, lasing, and quantum optics. He…

Accelerated Molecular Vibrational Decay and Suppressed Electronic Nonlinearities in Plasmonic Cavities through Coherent Raman Scattering

Lukas A. Jakob, William M. Deacon, Rakesh Arul +3

Molecular vibrations and their dynamics are of outstanding importance for electronic and thermal transport in nanoscale devices as well as for molecular catalysis. The vibrational…

Single-molecule mid-IR detection through vibrationally-assisted luminescence

Rohit Chikkaraddy, Rakesh Arul, Lukas A. Jakob +1

Room temperature detection of molecular vibrations in the mid-infrared (MIR, =3-30m) has numerous applications including real-time gas sensing, chemical reactivity, medical…

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…

Mid-infrared-perturbed Molecular Vibrational Signatures in Plasmonic Nanocavities

Rohit Chikkaraddy, Angelos Xomalis, Lukas A. Jakob +1

Recent developments in surface-enhanced Raman scattering (SERS) enable observation of single-bond vibrations in real-time at room temperature. By contrast, mid-infrared (MIR) vibra…

Direct phase mapping of the light scattered by single plasmonic nanoparticles

Otto Hauler, Frank Wackenhut, Lukas A. Jakob +5

In this work, we present a novel technique to directly measure the phase shift of the optical signal scattered by single plasmonic nanoparticles in a diffraction-limited laser focu…
