The present PhD proposal is open is the Nonlinear nanophotonics and quantum information team (TONIQ) of the Centre of Nanoscience and Nanotechnology (C2N), research laboratory of the CNRS and University Paris-Sud, born in June 2016, in order to meet to objectives : establish a flagship laboratory for research in nanoscience and nanotechnology, and provide a large technology facility to the Plateau de Saclay and the Ile-de-France region, open to all academic and industrial players in the field. The C2N gathers more than 120 researchers, and 80 engineers, technicians and administrative staff. C2N has a technology facility with more than 2800 sqm of cleanroom facility. TONIQ group is composed of 8 researchers and more than 10 PhD Students and Post doctorands.

The PhD thesis will be conducted in the frame of the French Agence Nationale de la Recherche, project NANOSTRONG, in collaboration with LKB at Jussieu and IOGS at Palaiseau.

Light-matter interaction at the single-quanta level is the keystone of quantum information science. However, single quanta are generally weakly interacting and enhancing this coupling has been the driving force for a large community and the development of the cavity quantum electrodynamics. Since few years, integrated photonic nanostructures appeared as a promising avenue of tailoring light-matter interaction by engineering the emitter environment. In this context, we explore the waveguide QED approach by trapping atoms close to photonic crystal waveguides exhibiting slowly propagating modes, reaching strong interaction without a cavity.

The main aim of the project is the optimization of the slow mode propagating in waveguides for both achieving strong coupling with single atoms and engineering of the collective response in mesoscopic populations, making strong atom-atom interaction mediated by the slow mode possible. The PhD student will have to design and simulate photonic crystal waveguides in order to exhibit slow modes at 780 nm, the resonance wavelength of rubidium atoms. She or He will contribute to the different steps of the fabrication process in the cleanroom facility of the laboratory. She or He will participate in the optical experiments to characterize the performance of the fabricated slow mode waveguides and will collaborate with Julien Laurat's team at LKB (Jussieu) in the atomic experiment.
