We study experimentally the oscillations of a nonstationary transient signal of a semiconductor microcavity with embedded InGaAs quantum wells. The oscillations occur as a result of quantum beats between the upper and lower polariton modes due to strong exciton-photon coupling in the microcavity sample (Rabi oscillations). The detection of a spectrally resolved signal has allowed for a separate observation of oscillations at the eigenfrequencies of two polariton modes. Surprisingly, the…

Dynamic stabilization of a polariton Rabi oscillator in the ground and inverted stationary states

The reported work describes different regimes of exciton-polariton oscillatory dynamics in a microcavity, in the conservative case as well as in the presence of continuous-wave pumping from the




We investigate a GaAs/(Ga,Al)As Fabry-Perot microcavity, into which (In,Ga)As quantum wells have been inserted. The cavity is wedge shaped, i.e., the detuning between the bare-exciton resonance and

Multiple-frequency quantum beats of quantum confined exciton states

Multiple quantum beats of a system of the coherently excited quantum confined exciton states in a high-quality heterostructure with a wide InGaAs/GaAs quantum well are experimentally detected by the

Time-resolved vacuum Rabi oscillations in a semiconductor quantum microcavity.

Femtosecond optical spectroscopy is used to observe directly the vacuum Rabi oscillations associated with the coupled exciton-photon mode splitting in a semiconductor quantum microcavity and shows the coherent evolution of the cavity polarization.

Dephasing effects on coherent exciton-polaritons and the breakdown of the strong coupling regime

Using femtosecond pump-probe spectroscopy, we identify excitation-induced dephasing as a major mechanism responsible for the breakdown of the strong coupling between excitons and photons in a

Coherent and incoherent aspects of polariton dynamics in semiconductor microcavities

The interaction between coherent polaritons and incoherent excitons plays an important role in polariton physics. Using resonant pump-probe spectroscopy with selective excitation of single polariton

Exciton-polariton oscillations in real space

We introduce and model spin-Rabi oscillations based on exciton-polaritons in semiconductor microcavities. The phase and polarization of oscillations can be controlled by resonant coherent pulses and

Relaxation oscillations in the formation of a polariton condensate.

Oscillations in the dynamics of a microcavity polariton condensate formed under pulsed nonresonant excitation may arise from relaxation oscillations, a pervasive classical dynamics that repeatedly provokes the sudden decay of a reservoir, shutting off relaxation as the reservoir is replenished.

Observation of spin beats at the Rabi frequency in microcavities

Rabi oscillations are observed in the optically induced time-resolved Faraday rotation from a strong-coupling microcavity. They reveal the dynamics of the excitonic part of the polariton state,

Ultrafast Control and Rabi Oscillations of Polaritons.

The setup precision and the system coherence are so high that coherent control can be implemented with amplification or switching off of the oscillations and even erasing of the polariton density by optical pulses.

Theory of quantum beats in optical transmission-correlation and pump-probe measurements.

A full density-matrix theory for quantum beats in optical transmission-correlation or pump-probe type of experiments is developed and it is demonstrated on the basis of perturbation theory that quantum beats should be observable in such experiments.
