Correlated photon emission from pyramidal quantum dot heterostructures

Martin Henrik Baier

Quantum dots (QDs) are nanoscopic semiconductor crystals. Electronic transitions inside QDs lead to photon emission with unique properties. Photons can for instance be emitted as triggered single photons or as pairs of correlated photons with different ene ...

Optimization of the efficiency of single photon sources based on quantum dots under optical excitation

Elyahou Kapon, Daniel Oberli, Martin Henrik Baier

We demonstrate efficient, regulated single-photon operation from site-controlled InGaAs quantum dots (QDs) grown on a prepatterned substrate. Under nonresonant optical excitation, carriers trapped at structural or compositional defects of the adjacent nano ...

Quantum Dot Exciton Dynamics Probed by Photon-Correlation Spectroscopy

Elyahou Kapon, Daniel Oberli, Martin Henrik Baier

The dynamics of charging and recombination of photoexcited, site-controlled semiconductor quantum dots (QDs) are investigated using microphotoluminescence (PL) and photon-correlation spectroscopy combined with rate equation modeling. Several species of neu ...
