Semiconductor microcavities (MCs) offer a unique system for producing and probing coherent states of matter. The bosonic nature of polaritons, the quasi-particles formed in these structures, and their very light mass can lead to the formation of non-equilibrium Bose-Einstein condensation. The interest in the fundamental properties of these structures is closely followed by technological advances such as inversionless ultralow threshold lasers, and micro-OPOs. Current efforts are devoted to developing novel MC-based photonic devices with both large Rabi splitting and exciton binding energy that can operate at room temperature. In this seminar, I will present our most recent results on polariton lasing at room temperature and on the spatio-temporal dynamics of polariton condensates.
