Post-docs and PhD students

Alexei started his PhD in january 2021. He is investigating the phase locking dynamics of integrated frequency comb lasers based on two types of technologies: the two section mode-locked laser and the single section frequency modulated comb laser.
Alexei is in a cotutelle between Nice  and ITMO University (Saint-Petersburg).

 

Benjamin started his PhD in september 2020. His works consists in the experimental study of the supercontinuum generation process. The phase stability of this nonlinear process is essential to build CEP stable OPCPAs. He is in cotutelle between UCA and Fastlite. This PhD thesis is part of the Marie Slodowska Curie actions.

Robin Matha has started his PhD in collaboration with ONERA in may 2021. He is developing new detection techniques based on self-mixing interferometry and deep learning algorythms.
Self-mixing interferometry is a technique for displacement measurement that has been known for a few decades. It is based on the interference between the photons of the beam in the intra-laser cavity and the photons reinjected into this cavity after reflection on a target in longitudinal motion. Self-mixing interferometry offers the possibility of creating new generations of sensors and accurate sensors, compact while having a low energy consumption. However, before obtaining such a result it is necessary to make the system more reliable by increasing the availability of the measurement and making the extraction of information in the signal more reliable.
