Pulse dynamics of the probe field inside the TQDs [panels (a), (c), (e), (g)] and the probe pulse at the sample exit [panels (b), (d), (f), (h)] as a function of time for different energy splittings: (a) and (b) ω42 = −ω43 = 0; (c) and (d) ω42 = −ω43 = 0.2γ; (e) and (f) ω42 = −ω43 = 0.4γ; (g) and (h) ω42 = −ω43 = 0.6γ; T2 = T3 = 1.35γ. The black solid line is the probe field at the entrance of TQDs and the blue solid line is the probe field at the exit, and the dotted line is the time sequence of the tunneling coupling T2 and T3. Other parameters are the same as those in Fig. 2.
