POSTES OUVERTS

Les postes suivants visent à renforcer l’action menée au sein du Contrat Plan Etat Région (CPER) Photonics for Society (P4S), ce projet fait l’objet du soutien financier du Conseil Régional Hauts de France, de la DRRT Hauts de France et du Fonds Européen de Développement Régional (FEDER).

Open Postdoc position 2018


Numerical simulations of light propagation in multimode non-uniform optical fibers

Mission :
The drawing tower facility FibertechLille of the PhLAM laboratory allows the
fabrication of optical fibers whose diameter varies with the propagation distance in a
controlled manner. The core of these fibers can be passive or active (Yb or Er doping) and the fiber can also be twisted. Different aspects of light propagation in these multimode and non-uniform fibers still have to be numerically studied both in the non-linear (short pulse) and in the linear (continuous wave) regime. According to his experience, the candidate will have to realize a numerical model in order to simulate the light propagation in one of these regimes in the aim to explain or to predict phenomena that can be experimentally observed. The model must take into account the specific features of the fiber : evolution of the longitudinal profile,
SPM/XPM between the different modes, heat generation in active fibers for laser amplifiers, bending radius, twist rate, etc. When possible, an analytical model allowing an easier interpretation of the studied phenomena will also have to be developed.

Candidate skills :

  • Experience in numerical simulations in guided optics
  • Intermediate knowledge of Matlab or C++

- Post-doctoral position in Photonics

  • Theme High energy and large band fiber optical parametric amplifier in topographic fibers
  • Research team : Nonlinear optics group of the photonic team, PHLAM laboratory, Lille, France. This team is based in the IRCICA institute.
  • Mission : The aim of the project is to develop high energetic large gain bands fiber optical parametric amplifiers at 1 μm. This project is in collaboration with the French atomic agency of Bordeaux. The candidate will have to design and characterize the fiber that will be fabricated in our own drawing tower facility FibertechLille. The group is composed of 9 people (3 permanents+6post doc/PhD students) and the lab very well equipped to conduct experiments (fs to cw lasers, high band pass oscillo, time lens system, optical sampling oscillo...).
  • Candidate skills : Experimental fiber optics, nonlinear optics, numerical simulations (Split step Fourier).
  • Duration} 1,5 years
  • Contact Prof. Arnaud Mussot (arnaud.mussot@univ-lille1.fr).
  • Starting date : before end 2017
