Outline of Final Research Achievements |
I have fabricated single photon sources with a single InAs quantum dot (QD), and its carrier dynamics were investigated. Originally introduced metal microcolumnar structure have enhanced the photon extraction efficiency up to 18 % from conventionally obtained 1% with planar structure. Charge states formed in the QD were modeled with 5-level system, and by comparing simulated time-evolution of the population with experimentally obtained correlation functions, I have successfully reproduced the carrier dynamics. This finding is crucial for controlling the carrier dynamics characterizing quantum photon sources.
