Assessing the Future of Smart Grid Technologies in Regional Energy Systems

Frédéric Louis François Babonneau, Guillaume Jean Tarel, Alain Haurie

In this paper we present the regional techno-economic model ETEM, designed for the analysis of regional energy/environment systems and we show how it can be used to explore the possible penetration of smart grid technologies in a region corresponding rough ...

Electronic and Optical Properties of Semiconductor Quantum Dots

Guillaume Jean Tarel

This thesis is devoted to theoretically study the systems of single quantum dots (QDs) embedded in various photonic nanostructures, in close relation with experimental data. The word single is essential: due to their nanometer size, QDs have mainly been st ...

Phonon-Mediated Coupling of InGaAs/GaAs Quantum-Dot Excitons to Photonic Crystal Cavities

Elyahou Kapon, Alok Rudra, Vincenzo Savona, Benjamin Dwir, Pascal Gallo, Kirill Atlasov, Guillaume Jean Tarel, Milan Calic

We demonstrate that the emission characteristics of site-controlled InGaAs/GaAs single quantum dots embedded in photonic crystal slab cavities correspond to single confined excitons coupled to cavity modes, unlike previous reports of similar systems based ...

Linear spectrum of a quantum dot coupled to a nanocavity

Vincenzo Savona, Guillaume Jean Tarel

We develop a theoretical formalism to model the linear spectrum of a quantum dot embedded in a high-quality cavity, in the presence of an arbitrary mechanism modifying the homogeneous spectrum of the quantum dot. Within the simple assumption of Lorentzian ...

Explanation of Photon Correlations in the Far-Off-Resonance Optical Emission from a Quantum-Dot-Cavity System

Vincenzo Savona, Guillaume Jean Tarel, Stefano Portolan

In a coupled quantum-dot–nanocavity system, the photoluminescence from an off-resonance cavity mode exhibits strong quantum correlations with the quantum-dot transitions, even though its autocorrelation function is classical. Using new pump-power dependent ...

Monte Carlo model for the photoluminescence kinetics of a quantum dot embedded in a nanocavity

Vincenzo Savona, Guillaume Jean Tarel

We address the problem of the photoluminescence of a quantum (QD) dot in a nanocavity, with focus on the case of nonzero detuning. In this regime, experiments have shown that strong emission from the cavity-like peak is still present for dot-cavity detunin ...

Ultralong-range radiative excitation transfer between quantum dots in a planar microcavity

Vincenzo Savona, Gaetano Parascandolo, Guillaume Jean Tarel

We study the system of two quantum dots lying on the central plane of a planar semiconductor microcavity. By solving the full Maxwell problem, we demonstrate that the rate of resonant excitation transfer between the two dots decays as d(-12) as a function ...
