Quantum fluctuations in a system of exciton polaritons in a semiconductor microcavity

Abstract

This paper analyzes how quantum fluctuations affect the properties of exciton polaritons in a sample located in a planar semiconductor microcavity. The analysis takes into account the nonlinear interaction between the excitons, even in the presence of a thermal reservoir. Exact solutions are obtained for the generalized Glauber P function in the adiabatic limit. Giant exciton bunching is predicted. It is found that the presence of quantum noise destabilizes a homogeneous solution that belongs to the lower bistability branch.

The impact of quantum fluctuations on the properties of quantum well excitons excited inside 0D semiconductor microcavity possessing strong light confinement is analysed. The analysis takes into account the exciton-exciton repulsion and the presence of a reservoir. Analytical solutions are obtained for the generalized Glauber P-function of the system in the adiabatic limit. Destabilization of the homogeneous nonlinear solution belonging to the lower bistability branch in the presence of quantum noise is predicted.

Quantum statistics of light emitted from a pillar microcavity

Timur A. Khudaiberganov, Igor Yu. Chestnov, Sergei M Arakelyan

Abstract A quantum behavior of the light emitted by exciton polaritons excited in a pillar semiconductor microcavity with embedded quantum well is investigated. Considering the bare excitons and photon modes as coupled quantum oscillators allows for an accurate accounting of the nonlinear and dissipative effects. In particular, using the method of quantum states presentation in a quantum phase space via quasiprobability functions (namely, a P-function and a Wigner function), we study the effect of the laser and the exciton-photon detuning on the second order correlation function of the emitted photons. We determine the conditions for the phenomena of bunching, giant bunching, and antibunching of the emitted light. In particular, we predict the effect of a giant bunching for the case of a large exciton to photon population ratio. Within the domain of parameters supporting a bistability regime we demonstrate the effect of bunching of photons.

Quantum optical effects in semiconductor microcavities

E. Giacobino, Jean‐Philippe Karr, Gaétan Messin +2 more

Investigations of quantum effects in semiconductor quantum-well microcavities interacting with laser light in the strong-coupling regime are presented. Modifications of quantum fluctuations of the outgoing light are expected due to the non-linearity originating from coherent exciton–exciton scattering. In the strong-coupling regime, this scattering translates into a four-wave mixing interaction between the mixed exciton–photon states, the polaritons. Squeezing and giant amplification of the polariton field and of the outgoing light field fluctuations are predicted. However, polariton–phonon scattering is shown to yield excess noise in the output field, which may destroy the non-classical effects. Experiments demonstrate evidence for giant amplification due to coherent four-wave mixing of polaritons. Noise reduction below the thermal noise level was also observed.

Photon statistics of semiconductor microcavity polaritons

Timur A. Khudaiberganov, Igor Yu. Chestnov, Sevak Demirchyan

Quantum statistical properties of the coherently driven semiconductor microcavity are studied. The unique quantum solution for the two-mode system of coupled excitons and photons was obtained in the adiabatic approximation. This solution predicts both bunching and antibunching regimes for the photonic field in the domain of parameters where the single mode polariton approximation fails.

Statistics of polaritons in the nonlinear regime

P. Schwendimann, Cristiano Ciuti, A. Quattropani

We discuss the quantum statistical properties of exciton polaritons in semiconductor microcavities. The nonlinear dynamics is treated within a model of interacting bosons for the signal, pump, and idler modes. We focus on the regime of parametric amplification below threshold. We present the time evolution of the signal and idler modes towards their stationary solutions and discuss their statistical properties. In particular, we evaluate the amount of squeezing of the radiation emitted out of the microcavity in a configuration, which may be relevant for experiments.
