Metallic nanojunctions support localised plasmon resonances and boost light matter interactions, but dynamical phenomena are poorly understood. Here, the authors report intrinsic photoluminescence blinking from plasmonic nanojunctions, originating fr

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

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 r

Monolayer transition metal dichalcogenides with direct bandgaps are emerging candidates for microelectronics, nano-photonics, and optoelectronics. Transferred onto photonic integrated circuits (PICs), these semiconductor materials have enabled new cl

We investigate an optomechanical platform to up-convert MIR-THz photons to the optical domain. The coherent conversion enabled by molecular transducers inside doubly resonant nano-antennas can reach single photon sensitivity, opening new MIR-THz dete

Nanophotonics VII.
When two sub-wavelength metallic nanoparticles, each of them supporting a resonant plasmon, are brought within few nanometers or less from each other, the two plasmonic resonances are strongly coupled. The new eigenmodes of the system include in part

The conventional explanation of plasmon-enhanced Raman scattering attributes the enhancement to the antenna effect focusing the electromagnetic field into sub-wavelength volumes. Here we introduce a new model that additionally accounts for the dynami

Nanocavities formed by ultrathin metallic gaps, such as the nanoparticle-on-mirror geometry, permit the reproducible engineering and enhancement of light-matter interaction thanks to mode volumes reaching the smallest values allowed by quantum mechan
