TE polarized reflectivity for the equilateral prism-coupled F8BT microcavity depicted in the inset. The left-hand side shows the angular reflectivity dependence measured using the line of a HeNe laser. The right-hand side shows the reflectivity spectrum obtained at an incidence angle of 73° in air. Solid red lines indicate fits to a transfer matrix-based model as discussed in the text.
Prism-coupled reflectivity spectra obtained for incidence angles, , in the range 60°–80°. The reflectivity scale is absolute, with the traces translated vertically and several intermediate angles omitted for clarity. Dashed red lines depict the evolution and anticrossing behavior of the reflectivity dips indicative of the strong coupling regime. The absorbance for a quantum dot film on glass (blue solid line) is given by the right-hand scale as indicated.
Dispersion relationship extracted from the reflectivity data of Fig. 2, plotted as a function of incidence angle in the glass substrate, . The blue dashed line indicates the bare cavity mode dispersion and the red solid lines represent a fit to the coupled oscillator Hamiltonian given in the text.
Mixing coefficients derived from the model in the text that describe the variation in photonic and excitonic character of the three polariton branches as a function of incidence angle. The labels and refer to the and excitons, respectively.
