Research paperExperimental CharacterizationStrongly nonlinear nanocavity exciton-polaritons in gate-tunable monolayer semiconductorsZhi Wang, Li He, Bumho Kim, Bo ZhenarXiv·2024·10.48550/arxiv.2411.16635·arXiv:2411.16635AbstractStrong coupling between light and matter in an optical cavity provides a pathway to giant polariton nonlinearity, where effective polariton-polariton interactions are mediated by materials’ nonlinear responses. The paper experimentally realizes nonlinear cavity exciton-polaritons by coupling a charge-tunable MoSe₂ monolayer to a photonic crystal nanocavity, showing that excitation-induced dephasing reduces exciton-photon coupling and drives a strong-to-weak coupling transition. The nanocavity enables all-optical switching at ultralow excitation energies and picosecond timescales.Read more
