Near-field active tips for plasmonics and quantum plasmonics
Surface plasmons (SPs) are modes of the electromagnetic field confined at the interface between a metal and a dielectric. Due to their hybrid nature, the SPs can be... -

Slow Diffusion of Light in a Cold Atomic Cloud
We study the diffusive propagation of multiply scattered light in an optically thick cloud of cold rubidium atoms illuminated by a quasiresonant laser beam. In the... -
Theoretical and experimental study of generation and quantum correlations of ...
This work deals about the study of coherence between triple photon beams generated by a third order non linear interaction. A protocol, based on the study of the field... -
Photonic chips for long distance quantum communication.
This thesis aim at showing the interest of using integrated optics to handle the topic of long distance quantum communication. Integrated optics brings on several... -

Squeezing frequency combs
We have developed the full theory of a synchronously pumped type I optical parametric oscillator (SPOPO). We derive expressions for the oscillation threshold and the... -
Towards A Quantum Memory For Non-Classical Light With Cold Atomic Ensembles
A reversible quantum memory allowing us to store and retrieve quantum information serves as a key necessity for implementing many of novel quantum information... -
Cooperative effects in cold atom clouds
In this thesis, we investigate experimentally as well as theoretically collective effects in dilute clouds of cold atoms. In order to study the competition between... -
Quantum electrodynamics in superconducting artificial atoms
Cette thèse porte sur deux problèmes théoriques d'électrodynamique quantique en circuits supraconducteurs. Nous avons d'abord étudié les conditions d'obtention du... -

Polaritons in semiconductor microcavities : quantum fluid dynamics, spin effe...
This work is devoted to the study of the properties of polaritons, half-matter/half-light particles, in a semiconductor microcavity. Their bosonic behaviour enables to... -
A quantum dot in a photonic wire : spectroscopy and optomechanics
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,... -
Electromagneically induced transparency and quantum memories on the D2 line o...
Because it allows a strong, controllable, and coherent light-matter interaction, electromagnetically induced transparency (EIT) is nowadays used in a wide range of... -
Entanglement of mesoscopic quantum fields for quantum communications
This thesis is concerned with different aspects of quantum information with the continuous variables of quantum states of light. Through the combination of the... -
