“…The polarization splittings can be additionally manipulated by modifying the geometry of the layers forming the cavity and Bragg mirrors, as discussed in Ref. [44]. Notice that the same SO-coupling engineering could be implemented for pure photons, either by choosing a larger exciton-photon detuning or processing an empty cavity.…”

We use coupled micropillars etched out of a semiconductor microcavity to engineer a spin-orbit Hamiltonian for photons and polaritons in a microstructure. The coupling between the spin and orbital momentum arises from the polarization-dependent confinement and tunneling of photons between adjacent micropillars arranged in the form of a hexagonal photonic molecule. It results in polariton eigenstates with distinct polarization patterns, which are revealed in photoluminescence experiments in the regime of polariton condensation. Thanks to the strong polariton nonlinearities, our system provides a photonic workbench for the quantum simulation of the interplay between interactions and spin-orbit effects, particularly when extended to two-dimensional lattices.

“…Second, the exciton states in the two separate cavities also form symmetric and antisymmetric combinations (ψ S , ψ AS ) given as ψ S = (φ 1 + φ 2 )/2 and ψ AS = (φ 1 − φ 2 )/2, where φ 1 and φ 2 are the single exciton wave functions in the two cavities 6,37 .…”

We have demonstrated coupling between a pair of ultrastrong light-matter coupled microcavities composed of neat glassy organic dye films between metallic (silver) mirrors at room temperature. Based upon our modified coupled oscillator model, we have observed that the degeneracy between the Rabi splittings associated with the symmetric and antisymmetric cavity modes is broken by the higher-order anti-resonant terms in the Hamiltonian associated with the breakdown of the rotating wave approximation in the ultrastrong coupling regime. These results are in quantitative agreement with both experiment and transfer matrix modeling. The component cavities are characterized by Q factors around 12 and display a large vacuum Rabi splitting around 1.12 eV between the upper and lower polariton branches, which is about 52% of the excited state energy, thus indicating ultrastrong coupling in each individual cavity. This large splitting is due to the large oscillator strength of the neat dye glass. We have also observed large polariton-induced incidence-side asymmetry in reflection spectra in a coupled cavity pair with one cavity having no exciton.

“…It is controlled by the optical thickness of the cavity as well as by the penetration depth of the photons into the mirrors. Therefore, the uncoupled cavity-photon mode can be described following the approach suggested by Panzarini et al [18] so that the cavity-photon mode energy (E C ) and the corresponding broadening (γ C ) is given by:…”
