Photon lattices and fluids of light

Our group studies the linear and nonlinear dynamics of light in photonic lattices and in semiconductor microcavities at the Univeristy of Lille-CNRS. Our current projects are:

Lattices of coupled micropillars

Semiconductor micropillars are an excellent platform to engineer lattices of photonic resonators with tailored bands. They allow the engineering and study of artificial gauge fields with photons, topological edge states, lasing in exotic modes, unconventional localisation. See more.

Lattice quantum electrodynamics in an open cavity

The coupling of quantum emitters to cavity environments modifies the emission properties. Semiconductor micropillars are an excellent platform to engineer lattices of photonic resonators with tailored bands. They allow the engineering and study of artificial gauge fields with photons, topological edge states, lasing in exotic modes, unconventional localisation. See more.

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, non-hermitian dynamics and nonlinear phenomena in discrete lattices. See more.

Out of equilibrium photon condensates and superfluids. Nonlinear effects in semiconductor microcavities 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. See more
