 Abstract: Ordered GaAs/AlGaAs quantum dots (QDs) are fabricated on patterned
GaAs(001) substrates and their optical properties are investigated by
microphotoluminescence (PL) spectroscopy. QDs exhibit sharp excitonic
lines with typical single QD emission features. Photon-correlation
spectroscopy shows single photon emission for the neutral exciton
transition. Polarization-dependent PL measurements reveal a sharp
exciton line and a fine structure exchange splitting of about 70 mu eV.
