Rémy BRAIVE, 2022 laureat of the Fabry – de Gramont Prize for his work around optomechanics with photonic crystals, in particular the use of mechanical modes for the generation of signals with high spectral purity and the detection of weak signals assisted by noise from phase.

Rémy BRAIVE has been carrying out his C2N research as a lecturer since 2009 at the University of Paris-Cité and since September 2021 a junior member of the Institut Universitaire de France (Fundamental Chair). During his doctorate in “Optics and Nanophotonics” at the Photonics and Nanostructures Laboratory (LPN), he examined the effects of quantum electrodynamics in cavities, the dynamic response and the coherence of low-threshold quantum dot nano-lasers using cavities. suspended photonic crystal. He then joined in 2018 the MPQ Garching (Germany) then the EPFL (Switzerland) as a post-doctoral student where he began to get involved in the fields of nano-optomechanics. Rémy BRAIVE thus demonstrated the strong phonon-photon coupling within two-dimensional photonic crystal cavities. Since 2009, he has carried out his research activities at the Center for Nanosciences and Nanotechnologies (C2N) of the CNRS and the University of Paris-Saclay. Leveraging its expertise in nanophotonics and nanofabrication with III-V semiconductors, its research themes are focused on innovative concepts taking advantage of the strong interaction between optics and acoustics. He thus launched new lines of research in nano-optomechanics in photonic crystals applied to the study of non-linear dynamic effects for the detection of weak signals and to the development of integrated optomechanical oscillators generating ultrapure modulation at frequencies microwave on an optical carrier. He is author and co-author of more than 58 scientific articles in international peer-reviewed journals and 2 patents. These results were also valued as a finalist for the Jean Jerphagnon Prize in 2021.
