(a) The transmitted intensity of the probe field Ut versus the incident intensity Uin for γb = γa = 0 (solid) and γb = γa = 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 Ωc = 0.2.
