Quantum Emitters Near a Metal Nanoparticle: Strong Coupling and Quenching

et al. 2014

We investigate the interplay between quenching and strong coupling in systems that include a collection of quantum emitters interacting with a metal nanoparticle. By using detailed numerical simulations and analytical modeling, we demonstrate that quantum emitters can exhibit strong coupling with the particle dipole resonance at distances at which the quenching to nonradiative channels is expected to dominate the dynamics. These results can be accounted for in terms of the pseudomode character of the higher multipole modes of the nanoparticle and the corresponding reduction of the induced loss rate. These findings expand the current understanding of light-matter interaction in plasmonic systems and could contribute to the development of novel quantum plasmonic platforms.

“…For an arbitrary position the Green tensor of a concentric multilayer sphere contains summations over spherical Bessel and Hankel functions of order n and their derivatives [22]. In the special case of an atom located at the center of the sphere, only spherical Bessel and Hankel functions of order one contribute.…”

“…The radius of the cavity R C is typically much smaller than the characteristic wavelength in the system, in which case the local-field effects become significant. The fact that the Green tensor of concentric spheres is known in closed form [20][21][22] makes this system well suited for an investigation of the effect of local-field correction on the atom-field interaction in the strong-coupling regime. Bragg-distributed dielectric microspheres can now be fabricated in laboratories using, for example, a combination of etching and chemical-vapor deposition [23], multistage emulsion polymerization [24], or thermal printing [25], meaning that the system under consideration is within the reach of today's experimental techniques.…”

“…For values of R C below this region of drastic change (not shown), together with line broadening, the plateau level rises fast in proportion with 1/R 3 C [Eq. (22)] and it can be expected that the strong-coupling regime, if it exists, would quickly disappear. This is also manifested in the behavior of the ratio /δω m [ Fig.…”

Local-field correction in the strong-coupling regime

2011

The influence of the local-field correction on the strong atom-field coupling regime are investigated using the real-cavity model. The atom is positioned at the center of a multilayer sphere. Three types of mirrors are considered: perfectly reflecting, Lorentz band gap, and Bragg-distributed ones, with special emphasis on experimental practicability. In particular, the influence of the local field on the spectral resonance lines, the Rabi oscillation frequency and decay rate, and the condition indicating the occurrence of the strong-coupling regime are studied in detail. It is shown that the local-field correction gives rise to a structureless plateau in the density of states of the electromagnetic field. The level of the plateau rises with increasing material density and/or absorption, which may eventually destroy the strong-coupling regime. The effect of the local field is especially pronounced at high-material densities due to direct energy transfer from the guest atom to the medium. At lower material density and/or absorption, variation of the material density does not seem to affect much the strong-coupling regime, except for a small shift in the resonance frequency.

The MoM solution by using the space‐domain free‐space dyadic Green's functions is obtained for a dielectric‐loaded slot antenna which is fed by a microstrip line laid on top of a DR strip. The simplicity and effectiveness of this method are demonstrated in this study. The flexibility of using a DR‐strip microstrip line is found in its adaptability to both flat and slightly curved surfaces. While the performance of this antenna is found to be as good as the same antenna fed by a conventional microstrip line, the high dielectric constant endowed with the DR material has a significant advantage over conventional microstrip lines in providing a better impedance matching for dielectric‐loaded slot antennas. The versatility of the space‐domain analysis method is also found to be greater than the spectral‐domain method. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 22: 202–205, 1999.
