Polariton are part-light, part matter quasiparticles originating from the strong-light matter coupling of excitons in various materials and photons in microcavities. Polaritons spontaneously decay from the microcavity due to the finite microcavity photon lifetime which provides a rich optical probe of the physics inherent in polaritonic systems. Striking phenomena polaritons can show are for example bosonic condensation, superfluidity and topological polaritons. In recent years, beside III-V semiconductors, new material systems have emerged for polariton lasers, such as organic molecules, perovskites and transitionmetal-dichalcogenides. In this presentation, we will provide an overview of recent developments in the field of polaritons in our group including various material systems.
