Quantum Spectroscopy of Plasmonic Nanostructures
We use frequency-entangled photons, generated via spontaneous parametric down conversion, to measure the broadband spectral response of an array of gold nanoparticles exhibiting Fano-type plasmon resonance. Refractive-index sensing of a liquid is performed by measuring the shift of the array resonan...
