Line Plot from Scientific Research

Left: the emission in the below-resonance range (E ≃ 1.26 eV), retrieved from a linecut in d, shows a non-negligible flux density at low angles (θ < 20°) for the in-plane dipole, followed by a dominant signal at higher angles (θ > 40°). The emission from the out-of-plane dipole gives a sizable flux density at high angles. This is in agreement with the observed emission in a. Right: the emission at exciton-cavity resonance (E ≃ 1.38 eV) is strong in the vicinity of 0° for the in-plane dipole owing to efficient cavity coupling. By contrast, a high-angle signal is still present for the out-of-plane dipole. Thus, the sudden change to 0° emission in the exciton-cavity matching condition of b is related to the selective cavity coupling of in-plane IX transition dipoles. The trend for E > 1.38 eV in d is consistent with the resonance observed in c.
