Polarization properties of strongly coupled exchange-split excitons and pillar microcavities
Abstract:
We demonstrate a combined experimental and theoretical investigation of the polarization properties of the strong coupling between fine structure-split excitons and anisotropy-split cavity modes. While the temperature is varied to control the light-matter coupling, we observe a notable change in the emission polarization for the branch of the exciton-like polariton. The exciton dephasing is introduced in order to explain the temperature-sensitive effect on the emission polarization. We apply the medium-dependent Green function approach involving the polarization-dependent exciton dephasing to model the emission spectra, which shows qualitative agreement with our experimental results.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
