TL;DR
This paper experimentally investigates Rayleigh scattering in coupled microcavities, revealing how disorder correlations induce inter-branch polariton scattering, which can be used to infer disorder characteristics.
Contribution
It demonstrates that disorder correlations in coupled microcavities cause inter-branch scattering, providing a new method to analyze disorder effects in such systems.
Findings
Disorder correlations lead to inter-branch scattering of polaritons.
Inter-branch scattering strength reveals disorder correlations.
Symmetry forbids inter-branch scattering without disorder correlations.
Abstract
We experimentally analyze Rayleigh scattering in coupled planar microcavities. We show that the correlations of the disorder in the two cavities lead to inter-branch scattering of polaritons, that would otherwise be forbidden by symmetry. These longitudinal correlations can be inferred from the strength of the inter-branch scattering.
