The calculated anisotropic transition probabilityΔM and the average transition probabilityM. The vertical lines and arrows indicate the transition positions of 1H1E, 2H1E, and 1L1E. The inset shows the calculated energy band alignment of In0.15Ga0.85As/GaAs/Al0.3Ga0.7As step QWs with segregation length of indium atoms l = 2.8 nm and internal field F = 12.3 kV/cm. Ec, Elh, Ehh, and Eso represent the energy band alignment of the electron band, light-hole band, heavy-hole band, and the spin-orbit split-off band, respectively.
