研究目的
Investigating the strong exciton–photon coupling in lead halide perovskites for potential applications in ultralow-threshold polariton lasers and quantum light sources.
研究成果
Large Rabi-splitting energy has been achieved in lead halide perovskites, indicating potential for polariton condensation and polariton lasers at higher temperatures or in low-Q cavities. The flexibility in dimensionality and elemental composition by low-cost fabrication makes perovskites advantageous for polaritonic applications. Future research should address challenges such as the coupling of quantum emitters to a cavity, lateral confinement and photonic crystal structure, and the dynamic process of polariton collective behaviors.
研究不足
The inhomogeneity and low Q factors of some perovskite materials restrain the stimulated polaritonic effects. The dynamic process of polariton collective behaviors and the influence of intrinsic properties in active materials need further investigation.
