Abstract
Several theoretical studies have recently suggested that the scattering of microcavity polaritons can be a source of non-classical photon correlations, producing photon pairs that are entangled in either the energy (branch index) [1], or the polarization degree of freedom [2]. Even cluster states can be generated [3]. Motivated by the above-mentioned proposals for the creation of entangled photon pairs, we studied parametric polariton scattering in 2D coupled planar and 1D microcavities grown by molecular beam epitaxy (Fig. 1, left hand side). The advantage of these structures is that the polariton branches involved in the parametric scattering are located energetically below the exciton reservoir, thus the particles are protected from excitonic losses, as shown in Fig. 1.
