Extraordinary optical transmission of multimode quantum correlations via localized surface plasmons

摘要

We demonstrate the coherent transduction of quantum noise reduction, orsqueezed light, by Ag localized surface plasmons (LSPs). Squeezed light,generated through four-wave-mixing in Rb vapor, is coupled to a Ag nanoholearray designed to exhibit LSP-mediated extraordinary-optical transmission (EOT)spectrally coincident with the squeezed light source at 795 nm. We demonstratethat quantum noise reduction as a function of transmission is found to matchclosely with linear attenuation models, thus demonstrating that thephoton-LSP-photon transduction process is coherent near the LSP resonance.
