Adrian Bartolo started his PhD in September 2018.  His work consists in the experimental study of the spatio-temporal self-organisation of light in an external cavity semiconductor mode-locked laser with large transverse beam dimension. The goal of his research is the obtention of 3D addressable localized light states in the output of the laser resonator, the so-called "light bullets". The research project is funded by the PRC ANR grant BLASON.

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.

Elizaveta
Elizaveta started her postdoctoral research in July 2020. She investigates third-order nonlinearity on the femtosecond time-scale. The project includes a development of the novel time-resolved ultrafast spectroscopy setup. This original approach is called "nonlinear Doppler interferometry" as the observable quantity is the frequency-shift of a weak probe pulse under the effect of an intense pump pulse in the nonlinear medium of interest.  The research project is funded by ANR.

Loïc Ramousse

Loïc started his PhD in march 2020. His work consists in studying applications of liquid crystals in ultrafast optic. Funded by the society FASTLITE the aim is to study and develop devices using the liquid crystal technology for pulse shaping in the femtosecond regime.

Evgeniy Saveliev

Evgeniy
Evgeniy
Evgeniy started his PhD in November 2018. His work is devoted to the study of the second harmonic generation in a lithium niobate single crystal with periodic structures. Evgeniy also studies proton exchange in lithium niobate single crystals and the effect of proton exchange on the kinetics of polarization switching.
He is in a cotutelle between UCA and UrFU (Ekaterinburg).This PhD thesis is funded by the French Government and the Russian Foundation for Basic Research.

Alexis Verschelde

Alexis
Alexis started his PhD in september 2018. His work is dedicated to the study of the coherence of swept source lasers, which are  laser sources nowadays massively produced for imaging applications such as Optical Coherence Tomography (OCT). He is investigating more specifically the real time coherence evolution of the MEMS-VCSEL during the sweep, which is supposed to remain single mode during the entire swept wavelength range, and aims at proposing all-optical or electro-optical systems to control and improve the laser coherence. This PhD thesis is funded by the french région Sud.
