Job Description

Nokia is providing Software, IT equipment and Services at the cutting edge of technology and adaptable to all types of Networks. To meet the needs of customers spread over 100 countries, our scientists and engineers are constantly innovating and developing future technologies that significantly transform the way people and objects interact. Powered by the innovation of Nokia Bell Labs, the company is at the forefront of creating the technologies that are increasingly at the heart of our connected lives. Nokia Bell Labs mission is to define the future of communications and networking and deliver disruptive innovations that redefine human existence and business realities. In Bell Labs, the Optical Transmission Department from the OSDR (Optical Systems and Device Research) Lab focuses on research aiming to design and demonstrate optical transmission systems and networks of the future that will connect cities, countries and continents.

While 3 billion people still lack broadband internet, non-terrestrial networks are promising complements to ground-based radio and fiber networks. However, today's radio frequency-based satellite systems are nearing their capacity limits and cannot be scaled further. Free-space optical technology is a natural alternative to deliver greater capacity and to better address data security needs. Once the most important remaining research challenges are resolved, they could rapidly expand and serve as a catalyst for the development of a new communication backbone in the sky, consisting of aerial and space optical nodes at different altitudes.

Responsibilities

As a PhD candidate, you will join the research team of the Optical Transmission Department in Bell Labs in Massy, France with renown expertise in the field of optical communications in space. You will contribute to the design of next generation cross-atmosphere optical satellites, particularly in constellations at LEO orbit. You will investigate efficient diversity techniques and adaptive transmission, turbulence mitigation techniques for ground-to-space optical links, including adaptive optics and digital signal processing. You will develop novel channel models accounting for time-varying distortions from air turbulence, select and test in the lab suitable optical interfaces for fiber-coupled optical transceivers for space/aerial links at >100Gbit/s, demonstrate a ground-to-LEO link using real-field turbulence data and work out the conditions for the best integration of such a link in the terrestrial fiber networks.

Co supervision of the research work will be provided by Institut d'Optique Graduate School through the doctoral school of the University of Bordeaux, France and by DLR in Munich, Germany.

The research activity will be sponsored by the Horizon Europe Marie Skłodowska-Curie Action (MSCA) Doctoral Networks (DN) FOCAL project. More information on the project can be found on the following URL: https://cordis.europa.eu/project/id/101169042

Applicants must comply with the rules of MSCA programs, in particular:

- The candidates must have a MSc (or an equivalent) degree in physics, optics, electrical, electronics or telecommunication engineering. Please provide degrees and MSs + BSc transcripts

- be of any nationality, but must not have resided or carried out main activity in the country of the host institution of the position they are applying, for more than 12 months in the last 36 months

- have not yet been awarded a PhD degree.

- The PhD program incorportes a 4 month secondment outside France, as predefined by the FOCAL consortium

We encourage the attachment of any document that can support the application, e.g. cover letter and recommendation letters.

Qualifications
