Présentation

Y. Léger, CNRS researcher at Institut FOTON, is an expert in semiconductor spectroscopy. His current research activity is focuses on the development of new nonlinear photonic circuits based on III-V semiconductors and especially gallium phosphide. He leads many aspects of this research, from theoretical predictions of nonlinear phenomena and design to nanofabrication and their optical characterizations. He is also involved in exploring the opto-electronic properties of emerging materials for energy which currently focuses on photoelectrochemistry of semiconductor electrodes. Before joinging CNRS, Y. Léger worked as a post-doc in B. Deveaud's group at EPFL where he explored the physics of excitons-polaritons in confined systems with main achievements in the observation of nonlinear excitations. and multistability phenomena. During his PhD thesis at the Néel Institute, he studied the magneto-optical properties of manganese-doped quantum dots, notably with the first observation of the optical signature of an individual magnetic atom integrated into a quantum dot.
