Our group studies the linear and nonlinear dynamics of light in photonic lattices and in semiconductor microcavities at the Univeristy of Lille-CNRS.
Topological photonics in lattices of micropillars
Semiconductor micropillars are an excellent platform to engineer lattices of photonic resonators with topological properties. They allow the study of artificial gauge fields with photons, lasing in topological modes, unconventional localisation, nonlinear topology…
Synthetic lattices in coupled fibre rings
Coupled fibre rings allow implementing time-multiplexed photonic lattices which propertis can be modulated in time and space with exquite control. This opens the door to the study of anomalous topological phases, aperiodic lattices with fractal properties, condensation and nonlinear phenomena…
Turbulence in a fluid of light
Nonlinear effects in semiconductor microcavities materials modify the properties of light to the point of making it behave as a dense fluid. Vortices, solitons, shock waves, turbulence or superfluidity are some of the most remarkable phenomena accessible in such fluids of light.
