Exciton-polaritons in ZnO microcavity resonators

We report on the observation of exciton-polaritons in all-oxide resonator structures with a quasi-bulk ZnO film as active medium at temperatures between 10 K and room temperature. The observed energy splitting of the exciton-polariton branches of about 76 meV in maximum reflects the resonator to be...

Description
Summary:We report on the observation of exciton-polaritons in all-oxide resonator structures with a quasi-bulk ZnO film as active medium at temperatures between 10 K and room temperature. The observed energy splitting of the exciton-polariton branches of about 76 meV in maximum reflects the resonator to be in the strong coupling regime.
