Polarization-dependent shift in excitonic Zeeman splitting of self-assembled InAlAs quantum dots

Abstract

We report the optical spectroscopic results of a single self-assembled InAlAs/Al GaAs quantum dot. The polarization-dependent shift of the Zeeman splitting in a single InAlAs QD has been observed. The induced Overhauser field is estimated to be 0.16 T in this InAlAs QD and the magnitude is shown to be controllable by the degree of circular polarization of excitation light.
