Abstract

We report the photoluminescence (PL) investigations of quasi-whispering gallery mode (quasi-WGM) polaritons in a ZnO microrod at room temperature. By using the confocal micro-PL spectroscopic technique, we observe the clear optical quasi-WGMs. These quasi-WGMs appeared in the ultraviolet (UV) emission region where the cavity modes strongly couple with excitons and form polaritons. The quasi-WGMs polaritons can be well described by the plane wave interference and the coupling oscillator model.

Schematic pictures of WGM polariton waveguide (a) and quasi-WGM polariton waveguide (b), (c) The WGMs (solid arrows) and quasi-WGMs (dashed arrows) appear in the TM polarized detection. The fitted red and green peaks with Lorentzian line shape correspond to WGMs and quasi-WGMs respectively. The inset, the PL spectra obtained at certain position of the microrod with unpolarized, TE and TM polarized detection, respectively. The dashed lines are guides for the eye.
