Research Abstract

Possibility of suppression of the dephasing effect in the semiconductor quantum dots was studied by a multi-wave mixing technique. The suppression effect of the coherence relaxation was observed under the irradiation of the control optical pulse to inhibit the dephasing effect. To study the origin of the suppression effect, we carefully investigated the optical response of the quantum dots and found the presence of the local field inside the quantum dots. The observed suppression effect can be qualitatively explained by the local field effect.
