Аннотация

Three-dimensionally confined Bragg microcavities exhibiting several fully quantized photon modes have been investigated by time-resolved photoluminescence spectroscopy. A strong decrease of the exciton lifetime with decreasing lateral dimension is observed and shown to be mainly due to coupling of the long-lived excitons with short-lived photon modes. We observe similar decay times of all photon modes for a fixed structure size which amount to approximately half of the corresponding exciton lifetimes. This behavior is explained by incoherent Auger-type scattering processes populating the photon modes on the low-energy side of the exciton line.
