Abstract

We report femtosecond pump and probe experiments in a semiconductor microcavity containing quantum wells. At high pump fields, the exciton-polariton Rabi doublet changes into a triplet structure. The triplet splitting increases as the square root of the input intensity. The transmitted probe intensity is modulated with the corresponding frequency versus pump-probe delay. The experimental results are discussed in terms of Mollow spectra of a saturated transition of a two-level system.
