Dr. Arnaud joined CEA-Leti in 2002 as a researcher working on breakthrough technologies for infrared imagers. Over the next 18 years, she held a variety of positions including Process Engineer and Laboratory Manager. In 2016, she was promoted to lead the Imaging Division, which gathers all the institute’s skills in design, technology, characterization and modeling for the development of imagers with spectral sensitivity ranging from visible light to THz. These works are carried out in close collaboration with industrial partners such as STMicroelectronics and LYNRED. 

She was promoted to head the Optics and Photonics Department in January 2020, where she is guiding more than 300 researchers involved in the conception and production of photonic devices and integrated systems in the fields of imagers, displays, communication systems and sensors. With a portfolio of 700 patents and more than €70 million annual external resources used to maintain a world-class infrastructure, the department is committed to ensuring that its teams offer their industrial partners excellence in research and collaboration.

During Dr. Arnaud’s career she also worked closely with CEA-Leti startup ULIS, now LYNRED, which merged with SOFRADIR in 2019. She earned a Ph.D. degree in optics, optoelectronics and microwaves from University Grenoble Alpes.

After a Ph.D. in Optoelectronics issued by INSA-Lyon, Dr. Fanget joined CEA-Leti in 2003 for a postdoctoral position on MEMS for adaptive optics. After tenure in 2005, he was in charge, as project leader, of several industrial partnerships focused on MEMS development for different applications. In this context, he supervised several PhD and trainees students and produced as author or co-author about 45 articles and 15 patents.

In 2011 he was promoted to lead the new Micro-actuator lab founded at CEA-LETI. The lab composed of about 20 researchers was focused on the development of  Piezoelectric  materials and their integration inside MEMS process for Optics, Acoustics, Haptics and Biomedical applications.

He was recently promoted in January 2019 to head the new founded Photonics Systems Section. The section composed of 3 Labs with about 80 researchers presents advanced expertise on optical system design, CMOS design and packaging. The section aims to move up the value chain until the optical function to better meet expectations of industrial partners. Addressing the system development allows to identify at early stage key innovations to be implemented inside future components. Main applications addressed are depth sensing (LIDAR), compact near eye device for projection (AR/XR) and RX/Gamma imagers for both medical diagnosis and safety.
