Abstract: Photoinduced intersubband absorption measurements in HgCdTe multiple quantum wells were reported. The transition energies and the linewidths were determined using a full 8×8 k·p Kane model approximation. Various in-plane effective masses for the first and second subbands should be taken into account in order to correctly fit the low energy side of the experimental spectra. The intersubband oscillator strength can be elucidated applying a nonparabolic band model and no excitonic improvement was observed.
