Photonics

The Fibre Optics and Applications team manufactures and studies specialty optical fibres for devices with applications in telecommunications, metrology, original laser sources for industry, biomedical or environmental monitoring. To optimize the performance of these components and subsystems we study the properties of the fibre materials and their modifications resulting from nano-structuring or doping operations, in particular rare-earth ions. The properties of the dopants in these materials depend on their environment and can be modified by the radiation to which they are subjected. These modifications are also studied in aging experiments (degradation under irradiation), sensitivity to power (optical damage, photo-induced attenuation). The team relies on the fibre optics manufacturing platform and its optical and spectroscopic characterization equipment.

The Complex Photonic Systems and Materials group specializes in the analysis of the fundamental physical properties of new optical components and architectures developed to meet the challenges of modern photonics such as advanced imaging, ultra-fast optics, neuromorphic photonics, integrated optics and biophotonics.
To meet these challenges, our research activities propose to develop new optical sources by integrating passive or active materials into complex architectures to manipulate and modulate the fundamental properties of light such as frequency, coherence, spatio-temporal dynamics and transport in complex optical networks.
The projects developed in our group rely on various experimental platforms such as liquid crystal devices for the manipulation of ultra-short laser pulses, nonlinear optics integrated on Lithium Niobate, and semiconductor materials and lasers emitting in the visible and near infra-red.

The Quantum Photonics & Information team is one of the leading group in the field of quantum photonics engineering and technologies. Its research topics lie in fundamental and applied quantum optics and information. More specifically, photonic systems operating in the telecom range are realized for demonstrating quantum supremacy in communication and metrology applications. Those devices, mostly based on integrated photonic circuits, make it possible to exploit simultaneously highly efficient nonlinear optical interactions and the active routing of information. This is an actual asset for the generation of on-demand engineered quantum states, based whether on discrete, continuous, or hybrid variables. These devices are developed in close collaboration with the Complex photonic systems and materials team and the Optics and photonics technological platform.
