Guilhem de Valicourt (Senior Member, IEEE) received the B.Sc. degree in applied physics from the National Institute of Applied Sciences (INSA), Toulouse, France, in 2008. From 2007 to 2008, he passed the Master of Science in photonics devices at the University of Essex, Colchester, U.K. In 2008, he joined Alcatel-Thales-CEA III-V Laboratory, where he was working on the design, fabrication, and characterization of reflective semiconductor optical amplifiers and directly modulated DFB lasers toward the Ph.D. degree. In 2011, he joined Alcatel-Lucent, France, as a Research Engineer on optical communication systems. In 2014, he joined Bell Labs, Murray Hill, NJ, USA. In 2017, he became a Principal Scientist at IPG Photonics, NJ, USA, where he started the silicon photonics activities. Since 2020, he has been the Director of photonic integration with Nubis Communications, New York NY, USA, a company that he co-started. His main research interests are focused on design, characterization, and applications of advanced integrated photonics devices (in InP, silicon, and hybrid III–V on silicon platform). He has authored or coauthored more than 120 scientific papers in journals and international conferences, four book chapters, and holds more than 35 patents. Mr. Valicourt received the 2011 Best Project Award from Alcatel-Lucent, the 2012 Marconi Young Scholar Award, the 2015 Harm Dorren Commemoration Award, and the 2019 IEEE Outstanding Young Professional Award.
