Emilien Peytavit received a Engineer degre from « Ecole Centrale de Lille » in 1999, and a PhD in Electrical Engineering from the University of Lille, France in 2002 for his work on terahertz generation by optical heterodyne techniques. As a Postdoc at the CEA-LETI in Grenoble France (2003-2005) he worked on microbolometer arrays for terahertz detection. From 2005 onwards he has been a CNRS Research Scientist based at IEMN at the University of Lille in France. He is author or co-author of 45 journal papers, 56 international conference papers and 3 patents.

His current research interests include:

  • Ultrafast Photodetectors and Integrated Photonics Circuits for microwave and THz photonics
  • THz Waveguides and Antennas based on III-V compounds and Silicon Microtechnology techniques
