Permanent staff researchers and professors:

Carlos Alonso-Ramos: Carlos Alonso-Ramos obtained his PhD in June 2014 at the Universidad de Málaga, Spain, on the development of high-performance integrated photonic circuits for chip interconnects and next generation coherent transceivers. Currently he is a CNRS researcher in the Center for Nanoscience and Nanotechnology (C2N) in Palaiseau, France. His research interest include the study of linear, nonlinear and optomechanical properties of silicon photonics circuits in the near- and mid-infrared for applications in telecom, sensing and quantum. He is in charge of the group of Micro and Nanophotonic devices on silicon since 2020.

Daniele Melati is a researcher at the Center for Nanoscience and Nanotechnology, France, and an Adjunct Professor at Carleton University, Canada. He obtained his PhD at Politecnico di Milano and he spent three years at the National Research Council Canada as Research Associate. His research focuses on the use of optimization and machine learning tools for the development of complex photonic devices, with recent applications to optical metalaterials and metasurfaces, photonic antennas, and optical phased arrays. He has co-authored more than 150 journal and conference publications and he received a European Research Council (ERC) starting grant in 2022 on the development of integrated devices for free-space optical communications.

Delphine Marris-Morini: Delphine Marris-Morini is a Professor at Paris Saclay University. Her research interests at the Center for Nanosciences and Nanotechnologies include silicon photonics in the near-IR and mid-IR wavelength range.She received an ERC starting grant (INsPIRE) on Ge-rich photonic integrated chips towards the mid-IR wavelength range for sensing and spectroscopic application. She received the bronze medal from CNRS in 2013. She published over 100 journal papers and she has been in charge of the group of Micro and Nanophotonic devices on silicon from 2015 to 2020.

Laurent Vivien: Dr Vivien is CNRS Director of Research at the Centre for Nanoscience and Nanotechnology (C2N), a joint Laboratory of CNRS, University of Paris Sud and University of Paris Saclay, France. Since 2016, he has also served as Deputy Director of C2N and Director of the Photonics Department. His research activities focus on the development of fundamental concepts for silicon photonics including optoelectronic and hybrid photonic devices. Especially, he participated to the demonstration of high-speed waveguide integrated germanium photodetectors and carrier depletion based silicon modulators. Dr Vivien has also been at the forefront of the development of hybrid integration of carbon nanotubes on Si photonics platform and recently on high-speed Pockels effect in strained silicon waveguides. In 2015, he received the European Research Council (ERC) grant as consolidator on the development of strained silicon photonics platform.

Eric Cassan: I am professor at the University. I have worked a lot on the themes of photonic crystals, slow waves, dispersion, etc., and my activity has focused a lot in recent years on hybrid photonics on silicon (2D materials, Erbium doped polymers, chalcogenides, etc.) for nonlinear optics on a chip. I really like computational physics and programming. On this activity or more related to experimental aspects, it is always a pleasure for me to welcome new students interested in research.

Delphin Dodane: Delphin Dodane received his MSE degree (Diplôme d'ingénieur) from Phelma engineering school in Grenoble (France), where he studied nanosciences and in particular Optics and Microelectronics. He also obtained a M.Sc. degree from Paris-Saclay University in Fundamental Optics. He made his research internship at Thales Research & Technology, the research lab of Thales, on the characterization of silicon photonics chips designed for LiDAR applications (within European project PLAT4M). He currently works towards the Ph.D. grade by developing integrated optical phase lock loops on InP chips at Thales, within the European project BlueSpace (H2020, 5GPPP).
