Development of a nanophotonic platform compatible with rubidium atoms and for enhancing the atom-photon interaction.


- Participate to the fabrication of new nanophotonic structures with slow modes at 780 nm, the resonant wavelength of the rubidium atoms.
- Set the optical experiments dedicated to characterise the performance of the fabricated nanostructures.
- Participate to the ongoing collaboration with LKB on the atomic experiment dedicated to the strong interaction of the cold Rb atoms with the optical modes propagating in the fabricated nanostructures.


- Have studied optics in general, nonlinear optics, quantum optics and atomic physics.
- be motivated to perform numerical simulation designs and to participate in the fabrication process and to work on optical/atomic experiments.
- Ability to work in a team, to interact with collaborators and with clean room engineers.

Work Context

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 (C-QED), where single atoms and single photons can be strongly coupled via a high-finesse cavity.

Integrated photonic nanostructures appear as a promising avenue for tailoring light-matter interaction by engineering the emitter environment. Modern nanofabrication techniques have indeed enabled to design solid-state systems with embedded emitters, such as quantum dots in photonic crystal waveguides or in nanocavities with high-quality factors, leading to Quantum Nanophotonics.

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, 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 main aim of the position is to pursue the work on this topic started few years ago and on which a PhD student on its third year is currently working. Over the last years we have been working on the design, the optimization of nanostructures compatible with Rb atoms, having an optical transition at 780 nm. The fabrication of the nanostructures in the clean room facilities of our center is ongoing with the first promising results and a stable fabrication process.
