Stephane received a degree of master in physics from the Universite Libre de Bruxelles (ULB), Belgium in 2006. From 2006 to 2010, he carried out his PhD work in the LIQ department of the Science Faculty & OPERA-photonique Department of the Applied Science Faculty of ULB thanks to a Doctoral fellowship of the Belgian Fund for Scientific Research (FRIA). Stephane PhD’s thesis was devoted to nonlinear and quantum optics using silicon photonics. He then worked at Cornell University (NY) in the group of Alexander Gaeta as a post-doc researcher from 2010 to 2014. Stephane joined INTEC in October 20014 and he is currently involved in the InSpectra project on Raman spectroscopy. Stephane’s topics of interest include: optical nonlinearities (chi3, chi2, Raman, carriers) in solid and vapors, all-optical processing, Raman spectroscopy, quantum optics circuitry, photon number sources, single photon detection.
