“…The starting point of our work is to consider M antennas as M polarizable objects with dipole moments () and to model their mutual interaction through the master microdisk cavity with a quasinormal-mode formalism. Previous related works include, on one hand, coupled-mode theory and Green’s function theory for polarizable objects coupled to resonators 4,30 and, on the other hand, works using QNMs for a semi-analytical model of the optical properties of a plasmonic resonator interacting with a single quantum object 31 , as well as with ensembles of classical dipolar oscillators 23,32 . The present model features two extensions.…”

We analyse the resonant mode structure and local density of states in high-Q hybrid plasmonic-photonic resonators composed of dielectric microdisks hybridized with pairs of plasmon antennas that are systematically swept in position through the cavity mode. On the one hand, this system is a classical realization of the cooperative resonant dipole–dipole interaction through a cavity mode, as is evident through predicted and measured resonance linewidths and shifts. At the same time, our work introduces the notion of ‘phased array’ antenna physics into plasmonic-photonic resonators. We predict that one may construct large local density of states (LDOS) enhancements exceeding those given by a single antenna, which are ‘chiral’ in the sense of correlating with the unidirectional injection of fluorescence into the cavity. We report an experiment probing the resonances of silicon nitride microdisks decorated with aluminium antenna dimers. Measurements directly confirm the predicted cooperative effects of the coupled dipole antennas as a function of the antenna spacing on the hybrid mode quality factors and resonance conditions.

An anisotropic quantum vacuum (AQV) has been predicted to induce quantum interferences during the spontaneous emission process in a V -atomic-transition. However, such effects of AQV are strongly limited by the lifetime of the excited states. Here, we predict a long-lifetime coherence in a Λ-atomic-transition, induced by the spontaneous emission in an AQV, without the need of a coherent laser field. Metasurfaces are used to design the AQV, which present the advantage of remote distant control. Detecting this coherence, in addition to be a new test of quantum electrodynamics, would demonstrate the remote control potential of metasurfaces, paving the way towards the control of interactions -such as coherent coupling -between quantum emitters, which is a key requirement to perform entanglement in quantum technology applications.

The spectral and spatial dependence of the resonant Lamb shift of an exciton inside a photonic vacuum field landscape is considered to predict an optical dipole potential generated via virtual photons quantum fluctuations. This trapping potential can be exploited for exciton self-positioning in electric field hotspots at the nanoscale in view of quantum electrodynamics effects. By non Hermitian decomposition of the electromagnetic Green tensor in terms of quasi normal modes, the resonant part of the Lamb shift is expressed as Fano profile strictly interlinked to the Purcell enhancement of the exciton radiative lifetime. This approach explains how to tailor the depth of the vacuum photonic potential in several possible scenarios.
