Ultrafast Transition From Coherent to Incoherent Polariton Nonlinearities in a Hybrid 1L-WS2/Plasmon Structure
Researchers employed 10‑fs two‑dimensional electronic spectroscopy to probe a hybrid monolayer WS₂ on a silver nanoslit array. The exciton‑plasmon strong coupling produced a 20‑fold increase in optical nonlinearity relative to uncoupled WS₂. Coherent Rabi oscillations with a ~64 fs period were observed within the first 70 fs, after which polaritons decohered into long‑lived dark states. A three‑oscillator model that includes bright and momentum‑dark excitons explains the dynamics and many‑body interaction effects.
