We have studied the dynamic properties of a single spin (Mn impurity or resident electron) in a II-VI semiconductor quantum dot. A quantum dot doped with a single Mn...

We have studied the spin dynamics of an individual Mn atom embedded a CdTe quantum dot. Our results show that the Mn spin relaxation is faster when the quantum dot...

This thesis presents the realization of an efficient single-photon source based on an InAs quantum dot integrated in a photonic nanowire. A photonic nanowire is a...

We have studied the growth and the properties of InAsP/InP(001) quantum dots made by metal-organic vapor phase epitaxy for the realization of 1.55 µm single photon...

After a continuous reduction which has begun 50 years ago, the feature size of electronic devices has now reached the nanometer scale, opening the door to quantum...

In the framework of this thesis, single InAs/GaAs quantum dot devices were studied by optical means. Starting with a general description of self-assembled InAs QDs,...

The thesis focuses on quantum optical effects in semiconducting artificial atoms. We first investigate theoretically a single emitter coupled to a one-dimensional...

This thesis work has focused on the synthesis of (In)GaN-based quantum dot (QD) structures by plasma-assisted molecular-beam epitaxy (PAMBE), deposited in both polar...

In this thesis we described a series of experimental works, which have been realized in the context of spin qubits, going from their use as information carriers to...

This PhD thesis focuses on the study of mode locked laser diodes based on novel optimized InAs Quantum Dash structures grown on InP substrates. It covers several...

This thesis is devoted to the study of current correlation of single-electron beams in a ballistic quantum conductor. A mesoscopic capacitor is used as an on-demand...

This thesis focuses on laser diodes made of Quantum Dot/Quantum Dash (QD) structures. These devices have attracted considerable attention due to their remarkable...
