Paper Abstract
The characteristics of exciton-polaritons in ZnO-based microcavities (MCs) are demonstrated with a large vacuum Rabi
splitting due to large exciton binding energy and oscillator strength. The lower polariton branches (LPBs) can be clearly
observed. For low temperature and large negative detuning conditions, a clear polariton relaxation bottleneck in bulk
ZnO-based MCs has been observed in angle-resolved photoluminescence measurements from 100 to 353 K at different
cavity-exciton detunings. The bottleneck is strongly suppressed with increasing the temperature and pumping power and
reducing detuning. This observed results supposed to be due to more efficient phonon-assisted relaxation and a longer
radiative lifetime of the polaritons. In addition, the linewidth broadening, blue-shift of the emission peak, and
polarization of polariton lasing from below threshold to up threshold are also discussed.
