Guilhem de Valicourt received the BSc degree in applied physics from the National Institute of applied Sciences (INSA), Toulouse, France, in 2008. From 2007 to 2008, he followed and passed the Master of Science in Photonics Devices at Essex University, U.K. In 2008, he joined Alcatel-Thales-CEA III-V lab where he was working on design, fabrication, and characterization of Reflective SOA and directly modulated DFB lasers for microwave photonic systems and next generation of optical access networks toward the Ph.D. In 2011 he joined Alcatel-Lucent Bell Labs in France as a research engineer and he is now a member of technical staff in Bell Labs USA since 2014. His main research interests are focused on design and characterization of advanced integrated photonics devices (in InP, silicon and hybrid III-V on silicon platform), optical packet transport and switching for metropolitan and wireless backhaul networks, technology for datacenters and access networks. He has authored or co-authored more than 80 scientific papers in journals and international conferences, two book chapters and holds 20 patents. He received the 2011 "Best project" award from Alcatel-Lucent Bootcamp, the 2012 Marconi Young Scholar award and was a finalist for the ParisTech Ph.D. prize in 2012.
