Photon statistics of semiconductor microcavity polaritons

Abstract

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.

Quantum statistical properties of the light emitted by a semiconductor microcavity with embedded quantum wells are studied. The unique quantum solution for the system of coupled excitonic and photonic modes was obtained. This solution predicts both bunching and antibunching of the photonic fraction of the condensate.

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.

The quantum features of the photon statistics in a semiconductor microcavity

Wei Wei

The quantum features of the temporal photon statistics of an exciton–cavity coupled system in a quantum-well semiconductor microcavity are investigated analytically. Under the secular approximation, if the nonlinear interactions, i.e. the exciton–exciton coupling and the phase-space filling, are much weaker than the exciton–photon interaction, the evolution of the Fano factor shows that the distribution of the photon numbers exhibits the feature of collapses–revivals (CRs), and the relevant revival time may be adjusted by several factors such as the total particle number, the detuning, and the nonlinear coupling strengths, etc. Especially, the ideal maximum antibunching with the minimum value 0 of the Fano factor occurs periodically for such a situation, with the dissipation of exciton–polariton being ignored.

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.

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

Sevak Demirchyan, Timur A. Khudaiberganov, Igor Yu. Chestnov +1 more

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.
