Abstract

Photon correlations in the emission of a two-atom system coupled to a core-shell plasmonic nanoparticle can be tuned. This theoretical and numerical investigation is relevant for technological applications requiring controllable light-emitting devices.

Tailoring the statistics of light emitted from two interacting quantum emitters

Adrián Juan-Delgado, Rubén Esteban, Álvaro Nodar +3 more

The interaction between quantum emitters leads to the formation of superradiant and subradiant states with possible applications in quantum technologies. To improve the characterization of light emission from these systems, we present here a systematic theoretical analysis of the intensity correlation from two strongly interacting quantum emitters at cryogenic temperatures as a function of the frequency and intensity of the excitation laser. This analysis effectively accounts for the effect of vibrational modes of the emitters and of phonons of the environment through the combined Debye-Waller/Franck-Condon factor. First, we analyze the color-blind intensity correlation and show that it can be tailored from strong antibunching to strong bunching by tuning the laser from the two-photon resonance to the transition frequency of the superradiant state. We also find a particularly complex behavior of the intensity correlation when the laser frequency is tuned to that of the transition of the subradiant state, giving raise to the possibility of emitting bunched and antibunched light depending on the laser intensity and the detuning between the two emitters. The numerical results are supported by analytical equations that can be used for the experimental characterization of the interacting emitters. Additionally, by selecting photons of particular frequencies, we analyze the rich landscape of frequency-resolved intensity correlations, which also depend on the laser detuning and intensity. The analysis of the frequency-resolved correlations provides further information about the different relaxation processes underlying the photon emission, unveiling one-photon and two-photon emission processes that cannot be resolved neither in the emission spectrum nor in the color-blind intensity correlation. These results show that two interacting emitters are a versatile and practical source of quantum light and highlight the usefulness of the intensity correlation to unveil complex dynamics in this system.

Photon statistics of a quantum emitter close to a lattice of plasmonic nanoparticles

F. Carreño, Vassilios Yannopapas, M. A. Antón +1 more

We study theoretically the statistics of photons generated by a quantum emitter located in the vicinity of a periodic plasmonic nanostructure. The presented formalism is based on a macroscopic QED formalism in conjunction with a density-matrix approach in order to obtain the second-order correlation function of the emitted photons accounting for the influence of the plasmonic environment. The metallic reservoir coupling is computed using Green's-function theory, which, for a periodic lattice of scatterers, is calculated by a multiple-scattering method. We show that the photon statistics and the antibunching of emitted photons depend very strongly on the orientation of the quantum emitter relative to the lattice, on the transition frequency of the emitter, on the intensity of the applied field, and on the geometrical parameters of the nanoparticles, such as the shell thickness.

Two-Time Intensity Correlation in a Driven V-Type Quantum Emitter Near a Plasmonic Nanostructure

Spyridon G. Kosionis, Vassilios Yannopapas, Emmanuel Paspalakis

We analyze the two-time intensity correlation function of the fluorescent field emitted by a three-level V-type quantum emitter located in the vicinity of a two-dimensional periodic plasmonic nanostructure. Due to the interaction of the quantum emitter with an electromagnetic field, the ground state population is excited to the upper levels, presenting decay due to spontaneous emission. The distinctive characteristic of this system is that the decay rates for a quantum emitter with dipole orientation perpendicular and normal to the surface of the nanostructure array exhibit large differences which vary with the distance between the quantum emitter and the two-dimensional nanoparticle array. This leads to simulation of quantum interference effects in spontaneous emission. By studying the dependence of the two-time intensity correlation function on specific physical parameters of the hybrid structure, including the intensity of the applied field, the detuning from resonance, the distance between the quantum emitter and the plasmonic nanostructure, as well as the spacing between the upper levels, we demonstrate a strong modification of the two-time intensity correlation functions. We also identify the conditions under which the two-time intensity correlation function is maximized, an effect which is associated to the bunching to antibunching transition of the emitted photons.
