Abstract

Polariton photoluminescence from cylindrical microcavities was studied under optical excitation below and above a nonlinear regime threshold. Lines of lateral excitonic polaritons quantization were observed in the spectra. In addition to quantization lines with a small orbital quantum number m, exciton-polariton whispering gallery modes with large m > 10 were observed in the cavities of relatively large diameter. In addition to the spectral distribution of the polariton size quantized modes, it was possible to observe their wavefunctions' spatial distribution.
