In semiconductor microcavities, exciton-polaritons are mixed light-matter quasi-particles arising from the strong coupling between photons and excitons. Due to their photonic component, polaritons can be coherently excited by an incident laser field and detected through the emitted light. Due to their excitonic component, polaritons interact, which can produce nonlinear effects and modify their dispersion curve. These properties have allowed us to demonstrate nonlinear and quantum optical effects in the microcavity emission as well as quantum fluid properties, superfluid motion, solitons and vortices. This opens new perspectives for quantum optronics as well as for quantum simulation.
