Franck Delmotte has been elected a Fellow Member of Optica.

Franck Delmotte, professor at the Institut d'Optique Graduate School (IOGS)/Paris Saclay University and head of the LCF's “XUV Optics” group since 2008, has been elected a Fellow Member of Optica.

Optica is dedicated to promoting the generation, application, archiving, and dissemination of knowledge in the field of light sciences. Founded in 1916, it is the leading organization for scientists, engineers, industry professionals, students, and anyone interested in this scientific field.

Optica Fellow status is limited to a maximum of ten percent of members and is reserved for those who have distinguished themselves through their contributions to the advancement of optics and photonics. Franck Delmotte was recognized for his pioneering contributions in the field of extreme ultraviolet (EUV) to X-ray optics.

After obtaining a PhD in applied sciences from the University of Paris-Sud in 1998, Franck joined the Charles Fabry Laboratory (LCF). He was Director of Studies at the Institut d'Optique from 2019 to 2024 and currently teaches optical thin films and X-ray optics.

He has made fundamental contributions to short-wavelength optics, which enable numerous scientific and technological applications, from extreme ultraviolet (EUV) to X-rays: dual-band mirrors for solar physics, attosecond pulse compression using multilayer mirrors, broadband diagnostics for laser fusion (Laser MégaJoule and National Ignition Facility), innovative optics for next-generation X-ray sources, and new interferential stacks with several world records for reflectivity.

He was responsible for developing multilayer optics for the two telescopes of the ESA/NASA Solar Orbiter mission launched in 2020. He is currently leading an international CNRS research project in collaboration with the Center for X-ray Optics, Lawrence Berkeley National Lab, and Lawrence Livermore National Lab (California).
