Theoretical and experimental studies were carried out on exciton-polaritons excited in ZnO. Polaritons in which both Γ 1 and Γ 5 excitons couple to electromagnetic waves simultaneously are shown to exist, and their signatures are observed in polarized reflectance spectra measured under k ⊥ a and E∥c configurations for an m-plane sample. Theoretical calculations reveal that the mixed-mode polaritons consist of one Γ 1 transverse mode and two Γ 5 longitudinal modes. It is also shown that the signatures are sensitive to the valence band ordering.
