Abstract
The optical response of Mott–Wannier excitons is investigated in semiconductor superlattices and microcavities. p-Polarized light is considered to calculate the reflectivity Rpand dispersion relation of the collective normal modes in superlattices accounting for extrinsic Morse potential wells, andRp in microcavities. Results of Rpexhibit well-defined peaks of the exciton bound states in the Morse potentials for both transverse and longitudinal modes. Comparisons ofRp with experimental reflectivity data of light for semiconductor microcavities exhibit good qualitative agreement as well as Rabi splitting.
