TLDR
In this paper, the second-order coherence of a parametric photon emission in a one-dimensional semiconductor microcavity optical parametric oscillator was investigated by means of a Hanbury Brown and Twiss setup.Abstract:
The statistic of parametric photon emission in a one-dimensional semiconductor microcavity optical parametric oscillator is reported. We perform photon-counting experiments on signal and idler beams by means of a Hanbury Brown and Twiss setup for studying the second-order coherence. Under pulsed laser excitation at normal incidence, energy-degenerate signal and idler beams are emitted in a mirror-symmetric configuration and share the same excitonic/photonic composition. Moreover the two emissions share the same intensity and the same coherence properties. We show that the bunching visibility [i.e., the value of g(2)(τ=0)] changes across the parametric threshold and it is associated both to different spectral composition of the emission and to the buildup of coherence at high injection. Nevertheless, different from conventional optical parametric oscillators, a full coherence is never recovered.read more

The road towards polaritonic devices
TL;DR: The most important features of exciton-polaritons in microcavities are reviewed, with a particular emphasis on the emerging technological applications, the use of new materials for room-temperature operation, and the possibility of exploiting polaritons for quantum computation and simulation.

Two-photon spectra of quantum emitters
TL;DR: In this article, the authors apply the theory of frequency-filtered and time-resolved N-photon correlations to study the twophoton spectra of a variety of systems of increasing complexity: single mode emitters with two limiting statistics (one harmonic oscillator or a two-level system) and the various combinations that arise from their coupling.

TL;DR: In this paper, the authors reported the first experimental demonstration of a genuinely quantum state of the microcavity polariton field, by swapping a photon for a polariton in a two-photon entangled state generated by parametric downconversion.

Correlation between Photons in two Coherent Beams of Light
R. Hanbury Brown,R. Q. Twiss +1 more
TL;DR: Hanbury-Brown and Twiss as mentioned in this paper showed that photon detections in the two daughter beams were correlated: the photons were bunching together, which corresponded to a correlation in the intensity of light in two beams, which could be used to infer the angular size of distant stars.

"Two-Photon" coincidence imaging with a classical source
TL;DR: It is found that any kind of coincidence imaging technique which uses a "bucket" detector in the test arm is incapable of imaging phase-only objects, whether a classical or quantum source is employed.
