(color online) Variations of α_mn with photon energy for DPQWs with different right well widths L_w2 and (a) L_b2 = 1 nm, (b) L_b2 = 2 nm, (c) L_b2 = 4 nm, (d) L_b2 = 2 nm and F = 15 kV/cm while the left well width L_w1 = 10 nm. The peak values indicate the main contribution of the transition of an electron from states m to n denoted by m–n in the panels.
