Continuous-wave frequency upconversion with a molecular optomechanical nanocavity

Tobias Kippenberg, Christophe Marcel Georges Galland, Sachin Suresh Verlekar, Wen Chen, Philippe Andreas Rölli, Sakthi Priya Amirtharaj

Coherent upconversion of terahertz and mid-infrared signals into visible light opens new horizons for spectroscopy, imaging, and sensing but represents a challenge for conventional nonlinear optics. Here, we used a plasmonic nanocavity hosting a few hundre ...

Intrinsic luminescence blinking from plasmonic nanojunctions

Tobias Kippenberg, Christophe Marcel Georges Galland, Giulia Tagliabue, Magalí Alejandra Lingenfelder, Sachin Suresh Verlekar, Wen Chen, Karla Banjac, Aqeel Ahmed, Philippe Andreas Rölli

Plasmonic nanojunctions, consisting of adjacent metal structures with nanometre gaps, can support localised plasmon resonances that boost light matter interactions and concentrate electromagnetic fields at the nanoscale. In this regime, the optical respons ...

Molecular Platform for Frequency Upconversion at the Single-Photon Level

Tobias Kippenberg, Christophe Marcel Georges Galland, Philippe Andreas Rölli

Direct detection of single photons at wavelengths beyond 2 mu m under ambient conditions remains an outstanding technological challenge. One promising approach is frequency upconversion into the visible (VIS) or near-infrared (NIR) domain, where single-pho ...
