概要
- 論文の詳細を見る
Triggered single-photon generation from InAlAs quantum dot (QD) was demonstrated for the first time. Emitted photonenergy coincides with high detection efficiency range of Si single-photon detectors, which is highly suitable for free-spacecommunication. Single-QD spectroscopy and crossed photon correlation measurements unambiguously revealed that severalemitting lines observed in a single mesa structure originated from the identical QD, and two temporary competing decayprocesses associated with neutral states and charged states were identified. Presence of the competing process is also inferredfrom an analysis of steady-state photoluminescence intensities. Formation process of charged exciton in QD is also discussed.
