Preparation and properties of ZnSe/(Zn, Cd)Se multi-quantum-well microcavities for room temperature polariton emission

摘要

Due to their large oscillator strengths, ZnSe microcavities with (Zn, Cd)Se quantum wells are particularly suited for investigation of the photon-exciton coupling behaviour in semiconductors. We have observed a strong coupling between the excitonic and photonic modes in a ZnSe microcavity with four (Zn, Cd)Se quantum wells and distributed Bragg mirrors of ZnS and YF3. A very large Rabi splitting hOmega > 40 meV was observed in temperature dependent photoluminescence investigations.
