Single Photons on Demand from Novel Site-Controlled GaAsN/ GaAsN:H Quantum Dots

Original Kurzfassung:
We demonstrate triggered single-photon emission
from a novel system of site-controlled quantum dots (QDs),
fabricated by exploiting the hydrogen-assisted, spatially selective
passivation of N atoms in dilute nitride semiconductors. Evidence of
this nonclassical behavior is provided by the observation of strong
antibunching in the autocorrelation histogram of the QD exciton
emission line. This class of site-controlled quantum emitters can be
exploited for the fabrication of new hybrid QD-nanocavity systems
of interest for future quantum technologies.
