title: Three-dimensional confinement of polaritons in ZnO microcylinder.
abstract: High quality ZnO microcylinders (MCDs), which naturally form three-dimensional (3D) optical microcavities, were synthesized by a simple vapor transportation deposition method. The exciton-polariton effects in these 3D microcavities were investigated through the angle-resolved micro-photoluminescence (µ-PL) mappings. By using the coupled oscillator model, the 3D confinement effect of polaritons, i.e., two-dimensional (2D) whispering gallery (WG) type confinement in the cross section of the ZnO MCD, overlapping with the one-dimensional (1D) Fabry-Pérot (F-P) type confinement along the c-axis, was well interpreted.
