Abstract ： The polarization dependence of conduction intersubband transitions in GaAs/AIGaAs step multiquantum well structures has been studied using infrared spectroscopy. For S-polarized 45°oblique angle incidence configuration with respect to sample surface normal, the transverse electric (TE) active intersubband transitions were observed. Both transverse electric and transverse magnetic (TM) active intersubband transitions were obtained in P-polarized incidence at 45°angle on sample, which shows a small energy splitting between TE and TM absorption peaks.
