The Refimeve Team

Christian Chardonnet is research director at the Centre National de la Recherche Scientifique (CNRS), a physicist and a former director of laboratoire de Physique des lasers of Université Sorbonne Paris Nord. He was the founder of the recently labelled French research infrastructure REFIMEVE concerning high precision time and frequency transfer by optical fiber at the European scale. He was deputy scientific director of CNRS for the domains of quantum, theoretical and laser physics (2005-2009). He was the Head of the department of research infrastructures at the French ministry of High Education, Research and Innovation from 2014 to 2019. During this period, he was a French delegate at ESFRI and was a member, then the chair of the Implementation group of ESFRI.

Paul-Eric Pottie received the Ph.D. degree in physics from University Pierre et Marie Curie, Paris, France, in 2003. Since 2012, he has been with LNE-SYRTE (now LTE), Paris, where he was involved in optical fiber links for ultraprecise time and frequency transfer over long-haul links and fiber networks. His current research interests include time and frequency metrology.

Etienne Cantin received the Ph.D. degree in physics from the Université de Bordeaux, Bordeaux, France, in 2015. He joined the Laboratoire de Physique des Lasers, Villetaneuse, France, and the Laboratory LNE-SYRTE (now LTE), Paris, France, where he was involved in optical fiber links for ultraprecise frequency transfer over long-haul links and fiber networks.

Anne Amy-Klein received the Ph.D. degree in physics from Université Paris 13, Villetaneuse, France, in 1990. In 1994, she joined the Group Metrology, Molecules and Fundamental Tests, Laboratoire de Physique des Lasers, Villetaneuse, where she has been the Lead since 2008. Her current research interests include optical fiber links, high-resolution molecular spectroscopy, laser stabilization, and optical frequency measurements.

Christophe Daussy received his Ph.D. in Physics from Université Paris 13, Villetaneuse, France, in 1999. He then joined the Laboratoire de Physique des Lasers. His current research interests include frequency metrology and physics education. He has contributed to parity non-conservation tests using laser spectroscopy, to the measurement of the Boltzmann constant for the redefinition of the kelvin, and to frequency transfer over optical fiber links.

Adèle Hilico received her Ph.D. in Physics from from University Pierre et Marie Curie, Paris, France, in 2014. In 2018, she was appointed as an Associate Professor at the University of Bordeaux, where she worked on the development of laser systems for quantum technologies — in particular, the implementation of low-noise high-power laser amplifiers in the infrared and high-power generation in the visible range. She recently joined the Laboratoire de Physique des Lasers to work on the development of low frequency-noise lasers and the distribution of frequency and time references via fiber links.
