Abstract: Lasing in a ZnO planar microcavity is reported under optical excitation up to room temperature. The cavity presents a quality factor of 450 and the simultaneous presence of two cavity modes with different interference orders. The transition from the strong coupling to the weak coupling regime is observed at lasing threshold. The gain mechanism below T = 240 K is attributed to excitons, according to the observation of a specific gain transition within the strong coupling regime. (© 2012 WILEY-VCH Verlag GmbH & Co.
