We report on the growth and optical studies of II-VI semiconductor parabolic quantum wells made of Cd1-xMnxTe for a broad range of quantum well widths and Mn molar fractions x. Photoluminescence excitation spectra revealed several series of peaks equidistant in energy associated with interband optical transitions between harmonic oscillator levels. From the analysis of the spectra the valence band offset Qhh = 0.44±0.1 was determined for the CdTe/Cd1-xMnxTe system.
