  bibo_abstract:
  - <jats:p>GaAs quantum dots (QDs) have recently emerged as state-of-the-art semiconductor
    sources of polarization-entangled photon pairs, however, without site-control
    capability. In this work, we present a systematic study of epitaxially grown GaAs/AlxGa1-xAs
    site-controlled pyramidal QDs possessing unrivaled excitonic uniformity in comparison
    to their InGaAs counterparts or GaAs QDs fabricated by other techniques. We have
    experimentally and systematically investigated the binding energy of biexcitons,
    highlighting the importance of the uniformity of all excitonic lines, rather than
    concentrating solely on the uniformity of the neutral exciton as a typical figure
    of merit, as it is normally done in the literature. We present optical signatures
    of GaAs QDs within a range of ∼250 meV with a remarkable uniformity within each
    individual sample, the ability to excite the biexciton state resonantly, and a
    systematic study of the fine-structure splitting (FSS) values—features important
    for polarization entangled photon emission. While, in general, we observe relatively
    large FSS distribution and associated non-uniformities, we discuss several strategies
    to suppress the average FSS values to &amp;lt;15 μeV.</jats:p>@eng
