Controlling Resonance Fluorescence Spectra and Photon Statistics in a Driven V-Type Quantum Emitter—Metal Nanoparticle Coupled Structure

We study the resonant fluorescence emission spectrum and intensity-intensity correlations of emitted fluorescent field by a V-type quantum emitter (QE) which is located near metal nanosphere. For description studied phenomena, we use density matrix equations methodology combined with electromagnetic calculations obtain results for profile second-order correlation functions associated photons. The decay rates coupling term exhibit strong dependence on distance that separates QE from nanoparticle. This also influences resonance QE. find that, in general case, composed five Lorentzian-type peaks, high interparticle distances, while, when very close to surface nanosphere, central becomes dominant, single-peaked spectral appears. two-time photons evolve an oscillatory manner around unity, non-zero time delay, period decreases increase intensity. In driving regime, antibunching bunching crossing does not depend distance, contrary found weak regime. laser under specific conditions, constantly remain region.
