On the coupling of two quantum dots through a cavity mode
The effective coupling of two distant quantum dots through virtual photon exchange in a semiconductor microcavity is studied. The experimental conditions for strong coupling and its manifestation in
Phonon-mediated off-resonant coupling effects in semiconductor quantum-dot lasers
The impact of non-resonant background emitters in semiconductor quantum-dot microcavity lasers is addressed within theoretical investigations based on the solution of the von Neumann equation.
9 – Luminescence spectra of quantum dots in microcavities
: The physics of strong light-matter coupling of a quantum dot in a microcavity is described at its most fundamental level, that of the Jaynes–Cummings Hamiltonian. Dissipation, dephasing and
Manifestation of the Purcell Effect in Current Transport through a Dot–Cavity–QED System
The Purcell effect enhances the current peaks through the cavity by increasing the cavity–reservoir coupling, while they decrease with increasing electron–photon coupling, and the resonant current peaks are also sensitive to the mean number of photons in the reservoir.

Asymmetric coupling between two quantum emitters
We study a prototypical model of two coupled two-level systems, where the competition between coherent and dissipative coupling gives rise to a rich phenomenology. In particular, we analyze the case
Dynamics of open quantum systems: excitons, cavities and surface plasmons
This Thesis is devoted to the interplay between coherence and decoherence in open quantum optical systems. Coherence in these systems is given by the interaction of matter with diferent kind of


Strong and weak coupling of two coupled qubits
I investigate the dynamics and power spectrum of two coupled qubits (two-level systems) under incoherent continuous pump and dissipation. New regimes of strong coupling are identified, which are due
Explanation of photon correlations in the far-off-resonance optical emission from a quantum-dot-cavity system.
New pump-power dependent photon-correlation measurements are demonstrated that this seemingly contradictory observation that has so far defied an explanation stems from cascaded cavity photon emission in transitions between excited multiexciton states.

The interaction of a two-level system with a single quantized mode of the radiation field of finite bandwidth in a thermal state and coupled to background vacuum modes is considered theoretically. A
Strong coupling of quantum dots in microcavities.
We show that strong coupling (SC) of light and matter as it is realized with quantum dots in microcavities differs substantially from the paradigm of atoms in optical cavities. The type of pumping
Nonlinear photoluminescence spectra from a quantum-dot–cavity system: Interplay of pump-induced stimulated emission and anharmonic cavity QED
We investigate the power-dependent photoluminescence spectra from a strongly coupled quantum dot-cavity system using a quantum master equation technique that accounts for incoherent pumping,
Scalable implementation of strongly coupled cavity-quantum dot devices
Using low temperature in situ optical lithography, we fabricate pillar microcavities with quality factors around 2×104. Each pillar embeds a spatially and spectrally resonant single InGaAs quantum
Photoluminescence of single quantum dots in microcavities
We study theoretically the photoluminescence of a single quantum dot in a microcavity under incoherent excitation. Analytical results including pure dephasing show that strong coupling and linewidths
The role of optical excitation power on the emission spectra of a strongly coupled quantum dot-micropillar system.
A strongly coupled quantum dot-micropillar cavity system is studied under variation of the excitation power, which yields a transition from strong coupling towards weak coupling which is mainly attributed to an exciton-photon coupling constant decrease.
On the spectroscopy of quantum dots in microcavities
At the occasion of the OECS conference in Madrid, we give a succinct account of some recent predictions in the spectroscopy of a quantum dot in a microcavity that remain to be observed
