Research progress in exciton polaritons in organic systems

Exciton-polaritons (EPs) is a quasiparticle formed by the strong coupling between photons and excitons of the semiconductors. EPs possesses characteristics such as fast photon speed, good coherence, and easy exciton controllability. Due to its bosonic nature, EPs can form Bose-Einstein condensation (BEC). Compared to inorganic systems, organic systems are more conducive to achieving BEC at room temperature, sparking widespread interest in the academic community. This article reviews the development of EPs, and provides an in-depth exploration of the mechanisms, BEC, superfluidity, vortex formation, and energy transfer in organic systems-based research.
