s-polarized reflectance as a function of the angle of incidence and photon energy for a δ/eV = − 0.37, b δ/eV = − 0.18 and c δ/eV = 0. The white, red, and black dashed curves correspond to the theoretical fitting of the energies of the lower, middle, and upper polariton respectively. d–f Spectral function, AL(θ, ω), calculated for the same detunings as in a–c. Middle polariton Hopfield coefficients for g δ/eV = − 0.37, h δ/eV = − 0.18 and i δ/eV = 0. The black, blue, and red curves correspond to the left cavity photon, right cavity photon, and exciton component, respectively.
