Strong-Coupling in Inorganic-Organic Hybrid Embedded Single and Coupled Metallic Microcavities

Abstract

Here we fabricated and studied highly-layered Inorganic-Organic Multiple Quantum Well structures and later placed them into metallic low quality factor microcavities. Room-temperature strong exciton-photon coupling is achieved in such single and coupled microcavities. Upon angle tuning, the broad photonic mode of the microcavities is clearly split into two modes at the exciton resonant absorption of hybrid perovskite. The large Rabi splitting upto -213 meV is obtained in good agreement with the theoretical models.
