Investigation of Excitonic Polaritons in ZnO Microcavities

Abstract

Cavity-coupled excitonic polaritons in ZnO microcavities is observed. The cavity is composed of ZnO wavelength (l)-cavity and high reflectivity distributed Bragg reflectors (DBRs). DBRs was composed of p- AlGaN/GaN, n-MgxZn1-xO/MgyZn1-yO, or SiO2/ZrO2 multiple quarter-wavelength (l/4) layers, and is also studied for future realization of threshold-free coherent light source that relies on Bose-Einstein condensation of cavity exciton-polaritons. Also, fundamental study of recombination mechanisms of excitonic polaritons in ZnO is also investigated. Fabrication and characterization of pn devices are planned to be carried out when strong coupling between exciton polaritons and cavity modes occur.
