Postdoctoral research officer position - Superradiance in cold rubidium confined in a hollow core photonic crystal fiber

About

XLIM (UMR 7252 CNRS/University of Limoges/University of Poitiers) is a multidisciplinary research institute located on several geographical sites: in Limoges, Brive and Poitiers. This post-doctoral work will be undertaken at the Gas-Phase Photonic and Microwave Materials group (GPPMM) at Xlim CNRS research Institute, University of Limoges, France. The GPPMM is world-renowned research group for its mix of experimental and theoretical investigations into new hollow-core photonic crystal fibres (HC-PCF) and their applications in nonlinear and quantum optics applications. The group works in an inventive and highly interactive environment, with internal interactions being complemented by active international collaborations. Limoges is a pleasant and attractive city in the west-central France, close to Bordeaux and 3 hours by train from Paris.

Job description:

To undertake a research project in a multi-disciplinary field at the frontier of atoms physics, fibre-photonics, cold atoms and lasers. The post-doctoral project aims to demonstrate superradiance in cold rubidium confined in a hollow core photonic crystal fiber, and assess it for the development of ultra-stable laser source. The research program requires (i) micro-confining and laser cooling rubidium atom inside the core of a hollow core fiber, (ii) exploring cooperative effects and (iii) generation and characterization of superradiance. The project is part of the FETOPEN project CRYST^3 funded by the European Research Council. The position is part of the European project CRYST^3. The latter aims to create a paradigm shift in the field of miniaturized quantum sensors. This implies, among other, (i) building an alkali-atom photonic-technology by tailoring HCPCF and PMC to the requirements of quantum sensing applications and accelerating their time-to-market; (ii) building innovative tools -and achieving seminal experimental demonstrations- for in-fiber cold-atom science and technology at the frontier of photonics, ultra-cold atoms and QED. A position is available and involves undertaking an original research project in experimental, numerical or theoretical atom optics in hollow-core photonic crystal fibres in an exciting and interdisciplinary environment. The research program requires mastering the following three disciplines: (i) photonic crystal fibre, (ii) atom optics and (iii) laser metrology.

The main tasks of the applicant will be:

  • • To work with others in the Gas-Phase Photonic and Microwave Materials group to design, fabricate and characterise hollow-core photonic crystal fibres (HCPCF) tailored for atom and cold atom optics.
  • • To work on optical experiments involving cold atom, HCPCF and signal processing.
  • • To prepare written reports for the project, to attend project meetings, and to interact with other parties involved in the project.
  • • To prepare scientific papers for publication, both in international journals and at conferences. To attend conferences in order to present the results of research and to interact with the broader scientific community.
  • • To work on related scientific projects as required
  • • To report on a regular basis to the project investigator
