Infrared absorption line profiles associated with transitions between the 1s-like ground state and 2p− excited state of hydrogenic donors in a quantum well are calculated for x-polarized radiation. Various types of dopant distribution are considered as in the experimental studies. Similarity is drawn between the calculated quasi-Lorentzian line shapes and one derived from a transmission spectrum for a central 1/3 barrier doped multiple quantum well sample. Effects in a magnetic field applied perpendicular to the layers are also investigated and compared with experiment.
