Microcavity polaritons: from quantum optics to quantum fluids

Abstract

In an optical cavity with a high finesse, one can generate strong coupling between light and matter. In such a system, the eigenstates are polaritons, which are mixed light-matter quasi-particles. We have studied the properties of polaritons in semi-conductor microcavities, where the active matter particles are bound electron-hole pairs, called excitons. Due to their photonic component, excitonpolaritons can be coherently excited by an external laser field and can be detected using the emitted light. Due to their excitonic component, polaritons interact with each other (Coulomb and Fermi interaction), which produces nonlinear effects [1] and modifies their dispersion curve.
