Поляритонные моды в цилиндрическом микрорезонаторе в режим поляритонного лазера

Abstract

The spectra of exciton-polariton photoluminescence from cylindrical microcavities under optical excitation below and above the threshold of transition to the polariton laser regime under conditions of strong exciton-photon coupling were studied. At relatively weak optical excitation, lateral quantization modes of polaritons and whispering gallery modes appeared. Both the spectral distribution of these modes and the spatial dependence of their wave functions in the resonator plane were observed. With an increase in the excitation intensity and a transition to the polariton laser regime, only one, the longest-wavelength lasing line remained in the spectrum. It has been suggested that under strong optical excitation, the spectrum contains not only exciton-polariton radiation, but also trion-polariton radiation.
