Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

Job description
We propose to study the spatiotemporal manipulation of radiation emitted by high harmonic generation, leveraging advances in nanofabrication technologies. The approach involves transposing methods developed for meta-optics to the strong-field regime specific to harmonic generation. The candidate will explore various design strategies to control the spatiotemporal properties of this radiation, which is intrinsically linked to the broad spectral bandwidth of attosecond pulses. These concepts will then be implemented and experimentally validated. This project aims to enhance the integration of high harmonic generation into optoelectronic devices, paving the way for new applications in ultrafast photonics.
