Given their unique structural properties, quantum rings (QRs) structures have recently been of particular interest for investigating quantum interference which is called the neutral charged exciton optical Aharonov-Bohm (AB) effect. A delocalized wavefunction around the rim is a prerequisite for the AB effect, but asymmetry and anisotropy seem to have been overlooked in the spectroscopy of QRs. In this thesis, the presence of a localized state in a single GaAs QR is presented.
