Abstract
Luminescence properties of thin-film cylindrical ZnO microcavities 1.8 µm in diameter obtained by electron-beam lithography and reactive ion etching were studied. Narrow luminescence peaks were detected in the excitonic and green spectral regions of zinc oxide and were attributed to spatial quantization of photon wave functions. It was found that stimulated ultraviolet luminescence arises with coupled photon modes of microcavities as optical pump power increases.
