摘要：
We study the interaction of quantum-well excitons with the electromagnetic normal modes of a multilayer dielectric cavity for finite in-plane wave vectors. In the strong-coupling regime we obtain the dispersion of the exciton polaritons by analyzing the exciton spectral function. We compare our numerical results with the recent angle-resolved photoluminescence data by Houdré et al. [Phys. Rev. Lett. 73, 2043 (1994)]. We find a very good agreement for the lower polariton branch and a discrepancy between theory and experiment for the upper polariton branch that is probably due to an experimental inaccuracy. © 1995 The American Physical Society.
