Abstract

The propagation of optical pulses resonant with the ground-to-excited state transition of InGaAs quantum dots is investigated. Analysis of low intensity excitation yields a dipole moment of 8.8 x 10e-29 to 10.9 x 10e-29 Cm, depending on quantum dot growth conditions. We observe polarization of the dipole moment exclusively in the plane perpendicular to the growth direction.
