Engineering Gaussian states of light from a planar microcavity

This is not the current version.
Quantum fluids of light in a nonlinear planar microcavity can exhibit
antibunched photon statistics at short distances due to repulsive polariton
interactions. We show that, despite the weakness of the nonlinearity, the
antibunching signal can be amplified orders of magnitude with an appropriate
free-space optics scheme to select and interfere output modes. Our results are
understood from the unconventional photon blockade perspective by analyzing the
approximate Gaussian output state of the microcavity. In a second part, we
illustrate how the temporal and spatial profile of the density-density
correlation function of a fluid of light can be reconstructed with free-space
optics. Also here the nontrivial (anti)bunching signal can be amplified
significantly by shaping the light emitted by the microcavity.

Author comments upon resubmission
We have adapted the manuscript according to the suggestions of both referees. In particular, a study has been added where we discuss the possible impact of various noise sources upon our proposed optical scheme.
List of changes
- We have added a paragraph in the introduction to motivate our work better. It is outlined why photons generated with the unconventional photon blockade can still bear interesting nonclassical features. Furthermore, we explain why the scheme that we propose may have more flexibility than other setups proposed in this context.
- We have added an Appendix (C), with references in the main text, where we discuss the effect of possible noise sources on the setup.
- The order of Figs. 1 and 2 was changed
- Some typo's where corrected
