| 摘要 | The optical polarization of GaN/AlGaN wurtzite quantum wells in various orientations is studied using an arbitrarily-oriented [hkilhkil] Hamiltonian potential matrix. The optical matrix elements in the wurtzite quantum wells are calculated using the k⋅pk⋅p finite difference scheme. The results reveal the presence of giant in-plane optical anisotropy (polarized normal to [0001]) in the M-plane (i.e., the View the MathML source(101¯0)-oriented layer plane) GaN/Al0.2Ga0.8N quantum well, due to the positive crystal-field split energy effect (ΔCR>0ΔCR>0). |
