Nonpolar ZnO/ZnMgO-based optical microcavities have been grown on (10-10) m-plane ZnO
substrates by plasma-assisted molecular beam epitaxy. Reflectivity measurements indicate an exponential
increase of the cavity quality factor with the number of layers in the distributed Bragg reflectors.
Most importantly, microreflectivity spectra recorded with a spot size in the order of 2 lm show
a negligible photonic disorder (well below 1 meV), leading to local quality factors equivalent to those
obtained by macroreflectivity. The anisotropic character of the nonpolar heterostructures manifests
itself both in the surface features, elongated parallel to the in-plane c direction, and in the optical
spectra, with two cavity modes being observed at different energies for orthogonal polarizations.
