Determination of anisotropic dipole moments in self-assembled quantum dots using Rabi oscillations
arXiv:cond-mat/0404398 · doi:10.1063/1.1646462
Abstract
By investigating the polarization-dependent Rabi oscillations using photoluminescence spectroscopy, we determined the respective transition dipole moments of the two excited excitonic states |Ex> and |Ey> of a single self-assembled quantum dot that are nondegenerate due to shape anisotropy. We find that the ratio of the two dipole moments is close to the physical elongation ratio of the quantum dot.
