摘要：

The size quantization of the excitonic polaritons in CdTe/Cd1-xMnxTe (x=0.1) multiple quantum wells was found in reflection and PLE spectra. The series of peaks above the heavy-hole exciton line were observed over a wide energy region in the PLE spectrum and the corresponding structures were seen also in the reflection spectrum. The energies of the peaks agree very well with a simple model of the quantum size effect of the excitonic polaritons. Additionally, subpicosecond time-domain measurements in transient reflectivity revealed oscillatory decay with two frequency components. The frequency difference between these components corresponds to the longitudinal-transverse splitting energy of excitonic polaritons at k=0.
