Raphaël ButtéRaphaël Butté was born in Paris, France, in 1973. He received the PhD degree from the University Claude Bernard, Lyon, France, in 2000 for his research on the structural and optoelectronic properties of hydrogenated nanostructured silicon thin films with potential applications for photovoltaics and thin film transistors. He then moved to the University of Sheffield (2000-2003), UK, to work as postdoctoral research associate in the group of Prof. Maurice S. Skolnick (Fellow of the Royal Society). His research shifted to the optical properties of III-V semiconductors with a main focus on the nonlinear optical properties of cavity polaritons occurring in GaAs-based microcavities driven under resonant optical excitation. In 2004, he moved to Ecole Polytechnique Fédérale de Lausanne (EPFL) as scientific collaborator in charge of optical spectroscopy at LASPE (http://laspe.epfl.ch/), a newly established laboratory directed by Prof. Nicolas Grandjean. In 2010, he became permanent member of staff (Scientific Collaborator and Lecturer). He was promoted to the position of Senior Scientist in 2016. His current research activity deals with planar waveguides, microdisks and photonic crystals made from III-nitride semiconductors. In particular, he is leading the activity focusing on: (i) the physics of exciton-polaritons in planar waveguides and (ii) high-β photonic crystal nanolasers. He is the author of 119 scientific articles published in peer-reviewed international journals, 14 publications published in peer reviewed journals following an international conference (Web of Science > 4500 citations, h-index: 36; Google Scholar > 6200 citations, h-index: 42) and 6 book chapters. He has given 30 invited talks in International Conferences/Winter-Summer Schools/Workshops. He has been the Publications Chair/Guest Editor of the Proceedings of the 5th International Workshop on Nitride semiconductors (IWN2008) and also served as Scientific Secretary of IWN2008 and of the 5th International Conference on Spontaneous Coherence in Excitonic Systems (ICSCE5). In 2012, he was one of the 149 scientists recognized by the Outstanding Referee program (http://publish.aps.org/OutstandingReferees) of the American Physical Society (APS) selected from a pool of roughly 60,000 currently active referees. Since September 2019, he is an Editorial Board Member of the newly launched open access APS journal, Physical Review Research. From September 2013 until December 2017, he was one of the Editors of the journal "Superlattices and Microstructures" (Elsevier). Since September 2015 he is a member of the Physics Doctoral School Teaching Committee. He was also a member of the EPFL Teaching Conference from September 2015 until August 2017. Jean-Philippe BrantutI did my PhD at the Institut d'Optique under the direction of Philippe Bouyer and Alain Aspect, before moving to ETHZ in the group of Tilman Esslinger, first as a post-doc then as a senior scientist. There I developed in particular the method allowing for a quantum simulation of nano-electronic devices with ultracold quantum gases.Since september 2016, I hold the Fondation Sandoz chair in physics of quantum gases at EPFL. There, my group has developed the first cold atoms machine combining Fermi gases with cavity-quantum electrodynamics. We use it to explore new ways of measuring and manipulating quantum matter.
Christophe Marcel Georges GallandI studied at Ecole Polytechnique in Paris (X2003) and received my PhD in 2010 from ETH Zürich for a thesis in solid-state quantum optics with individual carbon nanotubes, in the Quantum Photonics Group of Prof. Ataç Imamoglu. As a postdoctoral researcher at Los Alamos National Lab (USA) I studied the photophysics of individual nanocrystal quantum dots in the groups of Victor Klimov and Han Htoon. I was investigating the mechanisms responsible for fluorescence fluctuations and how to control them. I then moved to the University of Delaware in the group of Michael Hochberg to work in the emerging field of integrated quantum optics. I was leading international projects such as the realisation of an on-chip source of quantum correlated photons integrating optical filters and demultiplexers. From 2013 to 2016, I was working at EPFL in the group of Prof. Kippenberg in the field of quantum optomechanics with an Ambizione Fellowship of the Swiss National Science Foundation (SNSF). My work focused on the creation of non-classical vibrational states of mesoscopic oscillators and on the amplification of vibrations in molecules. Since May 2017, I am leading the Laboratory of Quantum and Nano-Optics at EPFL as an SNSF-funded professor in the Institute of Physics. My team investigates two main phenomena: (i) the vibrational dynamics of molecules embedded in nanoscale plasmonic cavities, and (ii) non-classical correlations mediated by individual quanta of crystal vibrations at room-temperature. We employ state-of-the-art spectroscopic tools such as femtosecond lasers and single-photon counters to get new insights into sub-nanometer scale dynamics.
Franz-Karl ReinhartOriginaire d'Oberdorf (SO), Franz-Karl Reinhart est né à Bassersdorf (ZH) le 12 juillet 1933. Diplômé ingénieur électricien à l'Ecole polytechnique fédérale de Zurich en 1958, il obtient son doctorat ès sciences techniques à l'Institut d'électronique avancée de l'EPFZ en 1962.
En 1963, il est membre du "Technical Staff" du Laboratoire de recherche en électronique à l'état solide chez Bell, à Murray Hill (New Jersey) aux Etats-Unis. Il s'intéresse à l'optique des ondes guidées, particulièrement à la modulation électro-optique dans les guides d'onde à jonction p-n, aux lasers semiconducteurs à injection et à l'optique intégrée monolithique. Depuis mars 1983, il est professeur ordinaire d'optoélectronique à l'Institut de physique appliquée et, depuis octobre 1987, à l'Institut de micro- et optoélectronique de l'EPFL. Il enseigne dans les domaines de l'optique et de la physique du solide. Il a développé les bases d'un laboratoire d'optoélectronique et de supraconductivité à haute température de transition.
Il s'intéresse principalement à la physique des semiconducteurs, à la supraconductivité et aux applications industrielles. Son activité primaire consiste en la préparation et l'étude de nouveaux matériaux et dispositifs quantiques pour les applications en micro- et optoélectronique.
Guanhao HuangDuring my bachelor’s study, I worked in Kim Kihwan’s trapped ion quantum computing group at the Insitutue for Interdisciplinary Information Sciences of Tsinghua University, China. I primarily worked on cryogenic helical RF resonators, and realizing beam splitter gates for boson sampling using ions’ motional states. Here at LPQM, I am currently working on the generation of non-classical quantum states in macroscopic systems through optomechanical interactions at room temperature, and also chip-based nanophotonic applications.
