Optically detected cyclotron resonance of two-dimensional electrons has been studied in nominally undoped CdTe (Cd,Mn)Te quantum wells. The enhancement of carrier quantum confinement results in an increase of the electron cyclotron mass from 0.099m0 to 0.112m0 with well width decreasing from 30 down to 3.6nm. Comparison with model calculations performed for this material system highlights two contributions to the mass increase, the first one determined by band structure parameters and the second one due to the polaron effect modified by reducing the dimensionality of the electronic system.
