Postdoc

Postdoctoral position on nanofabrication of silico photonic and phononic devices

The post-doc will be in charge of process development of silicon-on-insulator-based nanophotonic and phononic devices, in connection with two research groups respectively hosted at l’Institut Carnot de Bourgogne and at the FEMTO-ST Institute. He/she will operate in the MIMENTO clean-room facilities of the FEMTO-ST Institute in Besançon, France, one of the large French technological facilites belonging to the Basic Technology Research (BTR) network whose objective is to support the French institutional research.

Please send your application to aurelien.coillet@u-bourgogne.fr and sarah.benchabane@femto-st.fr

 
The position is for 1 year, and will start on December 13th at the latest.

Nonlinear nanophotonics

Job  profile:  The  candidate  will  have  to  design  and model  arrays of  gold  nanoantennas  in  order  to 
fabricate them in clean room. He/She will have to perform the nonlinear experiments to quantify the 
hot  electron  dynamics  and  their  related  saturable  absorption  in  the  fabricated  devices  (timescale, 
energy threshold…) at telecom wavelengths. Strong skills in nanophotonics and nonlinear optics are 
required. A background in fiber laser dynamics or in physics of ultrafast lasers could be valuable.

Please send your application to benoit.cluzel@u-bourgogne.fr

The position is for 1 year. Starting date: Automn-2017. 
Deadline: We will continue to advertise until a suitable candidate is found

Characterization of acoustic micro-antennas

Duration: 12 months
Place: Institut FEMTO-ST – Département Mécanique Appliquée, 25000 Besançon
Starting date: September 2017

Context
Various sensing technologies have been developed in the Smart Skins program funded by the labex ACTION (www.labex-action.fr). 
The present project aims at characterizing micro-machined sensors (CMUT) newly produced. Applications are related to non-destructive evaluation.


Missions
A first phase will be devoted to the characterization with various experimental apparatus and considering different operational conditions (materials, environment...). The multiphysics modeling will represent a second important facet of the project. Data analysis during mechanical tests will be tackled. This projects aims at responding to a double objective, “scientific” and “technological”. The candidate will thus be involved in the design and fabrication of a demonstrator illustrating the real time detection of elastic waves related to damages in composites for surveillance purposes.


Required profile:

  • PhD or experience in material science, wave propagation in solids, data analysis
  • Open to data science, instrumentation and experimental tests
  • Skills in programming, in particular Matlab
  • Skills in simulation in particular COMSOL. Interested in R&D, in search of innovative solutions
  • Team working, experience in interdisciplinary projects.

How to apply?
CV has be sent to emmanuel.ramasso@femto-st.fr in addition to any other information giving a hand to evaluate the quality of the candidate.

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.

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.
