Linear and Nonlinear Crystal Optics

Benoit Boulanger received the Ph.D. degree in material sciences from the University of Nancy in 1989. He was researcher at the National Center for Scientific Research (CNRS) from 1989 to 2000 at the University of Nancy, Stanford University, and the University of Bourgogne. In 2000, he joined the University of Grenoble-Alpes as Professor. He does his research at Institut Neel CNRS where he is a group leader. He held a position of Distinguished Professor at Tianjin University of Technology from 2018 to 2021. His work is at the frontiers between nonlinear crystal optics, quantum optics, and material engineering with achievements in frequency conversion and generation of new quantum states of light. He has authored over 350 papers in international peer-reviewed journals and conference proceedings. He teaches laser physics, nonlinear optics, crystallography, and tensors, and he also regularly gives tutorials on crystal parametric nonlinear optics in international conferences and summer schools. He served as associate editor for Optics Letters from 2014 to 2020. He was general co-chair of the international conferences Non Linear Optics (Hawaii) in 2013 and Advanced Solid State Lasers (Boston) in 2018, and will be general co-chair of the French-Israel Symposium on Non Linear & Quantum Optics from 2026.

Simon Joly is an associate professor at the University of Bordeaux in the IMS laboratory (Talence, France) since 2013 and is on delegation at the CEA of Pessac. He received his Ph.D. in Physics from the University of Grenoble in 2009. From 2010 to 2013, he undertook three postdoctoral positions at the Institute of Molecular Science in Okazaki, Japan, at the CROMA laboratory in Chambery, and then at CEA LETI in Grenoble. He has been involved in research activities in nonlinear optics, micro-lasers, terahertz spectroscopy, and infrared imaging. His current research focuses on two main areas: the development of photonic components for sensing applications and reliability concerns within the ONDES Research Group at the IMS Laboratory, and powerful and tunable sources for multispectral terahertz imaging at CEA Tech in Pessac.

Patricia Segonds received her PhD in physics from the University of Grenoble in 1989. During her postdoctoral fellowship at Ohio State University, she was appointed associate professor at the University of Bordeaux. She conducted research on ultrafast all-optical switching in glasses at the Centre de Physique Moleculaire et d'Optique Hertzienne (CPMOH) until joining the University of Grenoble-Alpes in 1998. She is currently a professor at the NEEL Institute, where her research deals with optics and frequency conversion in nonlinear crystals and their characterization and implementation in optical parametric oscillators. She has authored over 230 papers in peer-reviewed journals and conference proceedings. She teaches practical courses in linear and nonlinear optics and has recorded tutorials in various areas of physics. Since 2013, she has served the European Optical Society (EOS), 2022-2024 as President, 2024-2026 as responsible for the JEOS-RP journal. She has organized several EOS and OPTICA conferences.

Yannick Petit received the Ph.D. degree in physics of condensed matter and radiations from the University of Grenoble in 2007. He was a postdoctoral researcher in terawatt femtosecond laser applications at University of Geneva, Switzerland, from 2007 to 2010. In 2010, he joined the University of Bordeaux as associate professor. He does his research as a physicist at the Institute of Chemistry and Condensed Matter of Bordeaux (ICMCB). His work deals with femtosecond laser material structuring and 3D-printing for the development of photonic functionalities and integrated photonic circuits. He has authored over 100 papers in refereed journals and conference proceedings. He is teaching wave optics, nonlinear optics, and optics of solids in University of Bordeaux.
