Projects

I’m currently working on several research projects, please get in touch for further information.

Fluids of light

When light propagates in a nonlinear medium, it may behave as a quantum fluid. Thanks to a versatile optical setup, based on a photorefractive nonlinear crystal, we aim at studying experimentally various aspects of quantum hydrodynamics ranging from superfluidity to quantized vortices and wave condensation in complex landscapes.

Topological photonics

Topological insulators are materials that are electronically insulating in the bulk and perfectly conducting at the surface. The wave nature of their topological properties allows to bring it to the photonics realm with many targeted applications on robust light transport. Using microwave resonators or optical waveguide arrays, we aim at investigating the topological properties of photons in lattices in both static and Floquet regimes.

Femtosecond laser inscription of complex photonics structures

When an ultrashort laser is tightly focused inside transparent material, its optical properties (e.g. the refractive index) are permanently modified in the bulk at the nano/microscale. We developed this technique to inscribe complex photonics structures in various supports. Among others, we fabricate photonic lattices in glasses and nonlinear crystals to investigate the properties of light in discrete systems from the very quantum regime (photon pairs) to the extreme nonlinear regime (laser filamentation).
