Abstract
The usefulness of the concept of constant angle radiative intersubband polaritons in the description of the behavior of reflection-absorption spectra of bulk asymmetric microcavities with embedded multiple quantum wells is demonstrated. It is shown that a recently observed complex of the triple peaked absorption spectra of the above mentioned structures can be well reproduced employing expressions for the contribution of a single polariton mode to the microcavity absorption. The physical origin of the polariton modes responsible for the different peaks is also discussed.
