Arnaud has a master’s degree in “Physics, laser and materials” and a PhD in “Chemistry and Physics” (PhD thesis defended the 4 of December 2019). He comes from a “Physics, Laser and Materials” training, thus he has expertise in optical systems and in materials development and fabrication.
During his PhD, he worked on the development and purification of a new non-toxic (arsenic and antimony free) non-linear chalcogenide glass and on the purification of a tellurite glass for infrared transmission. The glasses were drawn into optical fiber to generate supercontinua (SC). The SCs were generated in all-solid (step-index) or suspended core fibers. He generated for the first time a SC from 1,5 to over 16 µm with a non-toxic chalcogenide fiber. These SCs were used to detect and quantify gases by absorption spectroscopy (CO2, CH4, N2O, publication in progress).
