Abstract
Semiconductor microcavity systems can display complex dynamics resulting from the coupling of excitons and photons to form cavity polaritons, as well as the creation of excitons that are localized by quantum-well interface fluctuations. We are performing experiments to probe the time-domain quantum dynamics of a semiconductor microcavity pumped above the band edge. Initial results show 20 – ps oscillations in the emitted light’s second-order coherence function, g(2)(t, t + τ), versus τ when the microcavity wavelength is tuned to a regime where localized excitons can reach lasing threshold at densities below the (saturation, or Mott) density where excitons ionize.1
