Title of the PhD project :
Development of ultrafast photonic measurements systems - application to measurements of relativistic electron bunches and terahertz pulses


Name of the PhD Director : Christophe Szwaj
Name of the co-director or collaborator : Serge Bielawski


Laboratory : PhLAM


Identified Research Programme(s) : CPER Photonics for Society


Summary of the PhD project :
The PhD project concerns the development of novel ultrafast systems for recording ultrafast electric or optical signals, with sub-picosecond time-scales. The main motivations concern the investigation of the relativistic electron bunches circulating in accelerators, as well as the terahertz pulses which may be produced by conventional lasers.

The work will require to develop new photonic concepts and strategies, that will allow real-time measurements to be performed. The foreseen strategies include (but are not limited to) the “photonic time-stretch” and “time lenses” strategies, which massively involves nonlinear optics and fiber optics.

The research work will also imply the measurements of relativistic electron bunch dynamics on different accelerators. The foreseen facilities are : Synchrotron SOLEIL (France), the FERMI free-electron laser (Trieste, Italy), KARA (Karlsruhe, Germany) and European XFEL at DESY (Hamburg, Germany). Applications on the measurement of “table-top” terahertz sources will also be investigated.

The research work involves experimental aspects in advanced nonlinear optics and fiber optics. It will also require numerical aspects (advanced data analysis, and numerical simulations during the design phases). The work will also require skills for work in collaboration in an international environment.
