(a) The transmitted intensity of the probe field U_t versus the incident intensity U_in for γ_b = γ_a = 0 (solid) and γ_b = γ_a = 1 (dashed). (b) Transmission (solid), reflection (dashed), and absorption (dotted) properties of the incident light versus detuning of the probe light in the presence of exciton spin relaxation. The used parameters are the same as those in Fig. 2 and Ω_c = 0.2.
