14. Resonators with YSZ as cavity instead of ZnO but otherwise with the same properties reveal Q -factor of about 350. The absorption of the ZnO layer makes a determination of the Q -factor impossible for the resonator presented here.

16. In Ref. it was shown by numerical calculation of the exciton-polariton branches that the ZnO B -exciton and C exciton also couple with the cavity photon. However these modes are also poorly developed and we did not see these modes, so we neglected this coupling as well as the coupling with the excited states.

18. The broadening is comparable to that of the cavity mode which we have observed in our resonator with a nonabsorbing cavity.
