Theoretical simulations of probe reflection (red curve) and transmission spectra (black curve). Panels (a) and (b) are for Doppler-broaden thermal atoms with u = 250 m/s, panel (b) is for the near-resonant expanded view in panel (a), the other parameters are the same as those in Fig. 3. Panel (c) is for the ultracold atoms driven by non-perfect SW with Ω_c2/Ω_c1 = 0.8. In numerical calculation, a single period is divided into l = 50 slices and the number of periods is set to be N = 1.6 × 10⁵.
