THz oscillations in the optical emission of a semiconductor microcavity

Summary form only given. The ultrafast optical emission of semiconductor microcavities has attracted considerable interest recently. Reported observations include coherent vacuum Rabi oscillations after weak resonant optical excitation, the emission of single pulses after nonresonant optical pumping, and relaxation oscillations after electrical pumping. We report here the first investigation of femtosecond time-resolved emission from a semiconductor microcavity resonantly excited with intense femtosecond pulses.
