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++

NONLINEAR DYNAMICS of OPTICAL SYSTEMS
The Nonlinear Dynamical of Optical Systems Group at the University of Lille announces the availability of a postdoctoral fellowship to study "EFFECTS OF NONLOCALITY AND NOISE ON NONLINEAR PROPAGATION THROUGH NEMATIC LIQUID CRYSTALS".

The main goal is to study the effects of nonlocality and stochasticity on nonlinear phenomena that occur during the propagation through a focusing non-instantaneous Kerr-like liquid crystal medium. Of particular interest are fundamental studies as well as control and management of light objects and trajectories such as localized states and wave singularities. In this way, we focus on the generation of spatial wave singularities (localization, shockwave, collapse, self-steepening, etc.).

The postdoctoral position is dedicated mainly to experimental but also to numerical aspects of this project. The ideal candidate should have a background in nonlinear dynamical systems, more precisely in transverse non-linear propagation and ideally in liquid crystals. Programming languages are C++ and MatLab. Experience with experiments is required.

Position and application details

  • The position is for one-year renewable and could start anytime before September the 31th, 2018
  • Net annual salary is about 25000€ for a debutant and includes a benefits package (health insurance, retirement, and unemployment benefits).
