2025 Postdoctoral Research Engineer in fiber optic sensing for environmental applications for 2 years
Fibre optics are now ubiquitous in our country for the transmission of high-speed telecommunications. In parallel with these developments, fibre optic sensors for monitoring power transmission, buildings and civil engineering structures have become widely used. In addition, since the measurement of water temperature in Lake Geneva in the late 1990s, fibre optic measurement methods and techniques have become much more diverse. It is now possible to measure vibrations along a fibre to measure seismic activity, to assess soil permeability by measuring underground water flow using active techniques, or to measure temperature along water columns in deep boreholes. There are several methods for distributed temperature measurement along an optical fibre and several point methods to diversify practical applications and meet different needs. All these instruments can be used simultaneously to provide more accurate information specific to experimental conditions.
The person recruited will be part of a collaborative project between the FEMTO-ST Institute (fibre optic sensors) and the chrono environnement laboratory (hydrogeology) to experiment, develop and implement distributed fibre optic sensor platforms for hydrogeological applications.
2025 Post Doc in photons / phonons interaction in tapered silica optical fibers for 2 years
The nonlinear optics group of the FEMTO-ST research institute at the University of Franche-Comté currently has a vacancy for a postdoctoral position working in the development of optical microfibers in view of potential applications to all-optical signal processing, lasers and optical sensors based on Brillouin scattering and related opto-acoustic
interactions. This project aims to investigate the remarkable opto-acoustic interactions in these tiny optical
waveguides to create novel optical processing techniques, compact narrow-linewidth lasers or ultrasensitive
optical sensorsand to achieve state-of-the-art characteristics.
The candidate must have a Ph. D in Physics or a related discipline, published research, extensive experience
in experimental optics, nonlinear optics and laser physics, knowledge in acoustics, experience with
numerical simulations and theoretical modelling, and experience in presenting seminars at conferences.
Interested candidates should send an enquiry, a CV including a list of publications and names and
addresses of referees to me at jeancharles.beugnot@femto-st.fr
