Biography

Dr Vivien is a CNRS Director of Research at the Centre for Nanoscience and Nanotechnology, a joint Laboratory of CNRS and University of Paris Saclay, France. He obtained his Ph.D. degree from Polytechnique School, Palaiseau, France in 2001 in pioneering work on nonlinear optical properties of carbon nanotubes for optical limiting applications. After two years as a postdoctoral researcher, he joined the Centre National de la Recherche Scientifique (CNRS) at the Institute of Fundamental electronic (IEF), Orsay, France. His research activities focus on the development of fundamental concepts for silicon photonics including optoelectronic and hybrid photonic devices. His team was among the first to demonstrate high-speed waveguide integrated germanium photodetectors, in collaboration with CEA-Leti and STMicroelectronics, and carrier depletion based silicon modulators. Dr Vivien has also been at the forefront of the development of high-speed Pockels effect in strained silicon waveguides, and of hybrid integration of carbon nanotubes and doped crystalline oxides on Si photonics platform. From 2006 to 2016, he was in charge of the Silicon Photonics Group at C2N (25 members). Since 2016, he has served as Deputy Director of C2N and Director of the Photonics Department. Between 2019 and 2020, Dr Vivien was invited to joint in the directory board of the Institute of Light Science, ISL (more than 800 members) from the University of Paris-Saclay to help of its setup. In 2021, with J. Michon (Fr, president & CEO), J.J. Hu from MIT (USA), and D. Kita from Ayar Labs (USA), he cofounded the start-up company InSpek-solution for the development of Integrated sensors (https://www.inspek-solutions.com).
As a leading expert in silicon photonics, Dr Vivien is regularly invited to prestigious international conferences including plenary, tutorial and keynote talks. Among the distinctions for high impact research performed in his group, he received in 2015 the Consolidator European Research Council (ERC) grant on strained silicon photonics and in 2023 the Advanced European Research Council (ERC) grant on the hybrid integration of doped crystalline oxides in silicon photonics. He is also an elected Fellow of the Optica, the European Optical Society (EOS) and of the International Society for Optics and Photonics (SPIE). He regularly serves as a Chair or a program committee member of SPIE, EOS, OSA and IEEE conferences on photonics and optoelectronics.
