Fig. 4: Corner state cavity symmetry and polarization characterization.
From: Single photon emitter deterministically coupled to a topological corner state
a The intensity of emitted photons from the charged exciton X+ plotted as a function of the angle of the half-wave plate, showing both on-resonance with the cavity mode (red) and in bulk material (blue). The linear polarizabilities are calculated as 96% and 61%, respectively. b The Hz component of the corner state mode profile, which exhibits a specific pattern and symmetry, which providing crucial insights into the polarization effects of the cavity. c, d Hz component of dipole radiation for two different orientations of the dipole: 45o (c) and 135o (d). The direction of the arrow indicates the orientation of the dipole. By comparing these plots with the Hz component of the corner state mode profile (shown in Fig. 4b), the coupling and modulation effects of the cavity on the dipole with different orientations can be analyzed
