Abstract
We present measurements of the vacuum Rabi splittings associated with the fundamental and the first three excited magnetoexcitons in a semiconductor microcavity up to 9 T. The oscillator strength values which are deduced from these experiments are compared to a simple and original variational calculation which includes the low magnetic-field (excitonlike) limit and the high magnetic-field (cyclotronlike) limit. Theoretical and experimental results are compared and discussed.
