I am a researcher at the Center of Nanoscience and Nanotechnology (C2N), Palaiseau, France. I am working in the fields of nonlinear and quantum optics and nanophotonics. My main research activities are dedicated to : - generation and study of quantum properties of triplet photon states - multipartite entanglement in nonlinear waveguide arrays - strong atom-photon interaction using slow mode in photonic crystal waveguides.
