Semiconductor plasmonics

The position is for 1 year with possible extension.
Starting date: Mid-2017

The Near-field Optics Group at Université de Bourgogne Franche-Comté invites applications for a postdoc. The focus of the project is on semiconductor plasmonics and is detailed hereafter. Only candidates with related experience should apply. We are looking for a motivated researcher to join our young and dynamic team on an innovative research project funded by the LABEX ACTION (http://www.labex-action.fr/). You must hold a PhD in an experimentally related area, ideally in time resolved Raman spectroscopy or in semiconductor plasmonics. Analytical and programming skills (Matlab, Comsol, Labview…) are a strong added-value.

Submission documents:

  1. A cover letter where you introduce yourself, your past research achievements and your career goals.
  2. A full CV including undergraduate and postgraduate details.
  3. Details of at least two academic referees we can contact.


Deadline: We will continue to advertise until a suitable candidate is found.

Please send your application to olivier.demichel {at} u-bourgogne.fr

 

NONLINEAR FIBER OPTICS FOR ULTRAFAST SIGNAL PROCESSING

One year Postdoctoral Fellow position funded by the Region Bourgogne/Franche-Comté is opened at the SLCO group in the context of the Laboratory of Excellence Action.

The research is related to the use of nonlinear fiber optics for all-optical ultrafast signal processing. In particular, the position aims at exploring new effects related to nonlinear temporal
and spectral pulse shaping, wavelength conversion and application of dispersion managed fibers.
Studies investigating the impact of partially coherent waves will also be initiated. Research will rely on state-of-the-art testbeds devoted to high-speed optical telecommunications. Proof of principle experiments dealing with signals at 10 and 40 Gbps will be carried-out. Other experiments dealing nonlinear effects affecting fiber amplification will also be undertaken.


The candidate must have a Ph.D in Physics or a related discipline and published research. The applicant must be an experimentalist with a solid background in at least two of these fields : fiber
optics, nonlinear optics, optical telecommunications or picosecond temporal and spectral pulse characterization. Good skills in numerical simulations will be appreciated.

Good knowledge of spoken and written English or/and French is mandatory.

The starting of the contract must take place before the end of year 2016.
