Polariton-biexciton transitions in a semiconductor microcavity

Summary form only given. Recent pump-and-probe measurements performed on the exciton-polariton in GaAs-based microcavities have been interpreted in terms of contributions due to biexcitons. Inspired by these initial hints we investigated a microcavity containing a single 5 nm ZnSe quantum well which...

Description
Summary:Summary form only given. Recent pump-and-probe measurements performed on the exciton-polariton in GaAs-based microcavities have been interpreted in terms of contributions due to biexcitons. Inspired by these initial hints we investigated a microcavity containing a single 5 nm ZnSe quantum well which provides large biexciton binding energies and small exciton linewidths. As a result we report here the first direct observation of a spectrally isolated, pump-induced resonance due to polariton-biexciton transitions in a microcavity.
