Dr. Bertrand Dutoit is at the head of applied Superconductivity Group at EPFL. He has worked in many aspects of applied superconductivity, he did a PhD work on dynamic magneto-optical observation of intermediate state in type I superconductors. He did high precision transport AC losses measurements in High Temperature Superconductors (HTS) at EPFL. His main activities are now on superconducting device numerical modelling with Finite Elements (FEM), AC losses calculations, HTS cables, Fault Current Limiters (FCL), dynamical Hall probes magnetic field mapping, quench measurements and heat transfer measurements. He is member of the IEA HTS Implementing Agreement Executive Committee.
Prof. Luc Thevenaz leads a research group involved in photonics, namely fibre optics and optical sensing.
Research topics include Brillouin-scattering fibre sensors, nonlinear fibre optics, slow & fast light and laser spectroscopy in gases.
His main achievements are:
- the invention of a novel configuration for distributed Brillouin fibre sensing based on a single laser source, resulting in a high intrinsic stability making for the first time field measurements possible,
- the first experimental demonstration of optically-controlled slow & fast light in optical fibres, realized at ambient temperature and operating at any wavelength since based on stimulated Brillouin scattering. The first negative group velocity of light was also realized in optical fibres using this approach.
- He is author or co-author of some 400 publications and 9 patents. He is Member of the Editorial Board (Associate Editor) for the journals "Nature Scientific Reports", "IEEE Photonics Technology Letters", "Laser & Photonics Reviews" and "Nanophotonics". He is also Senior Member of the IEEE and Fellow of the Optical Society of America
