Research at the MPQ Laboratory deals with the study of quantum phenomena in nanomaterials down to the atomic scale. It is centered around three themes: nanomaterials, electronic properties and quantum optics, bringing together several communities with both experimentalists and theoreticians. We aim at elaborating quantum devices based on this fundamental research, often in collaboration with industry such as Thales and Onera, as well as French start-ups. I will overview our activity in photonics, THz detection and micro and nano-optomechanical devices, and focus on semiconductor optical parametric micro-oscillators and integrated twin photon sources.

Giuseppe Leo (born in 1966) received a Master in EE at “La Sapienza” University of Rome (Italy) and a PhD in Physics at the University of Orsay (France). From 1992 to 2004 he has been with the Rome-III University as assistant professor and then as associate professor. Since 2004 he has been full professor at the Paris Diderot University (France) and Head of the Nonlinear Devices group of MPQ Laboratory since 2006. His research domains include nonlinear optics and quantum optoelectronics, with a focus on AlGaAs platform. Dr. Leo has coordinated several research projects, published about 100 articles, 9 book chapters and >150 conference papers, edited 1 book and registered 4 patents. He is the director of the Denis Diderot School of Engineering.
