Abstract

Integrating In(0.3)Ga(0.7)As quantum dots (QDs) featuring a high oscillator strength into a high quality electrically contacted micropillar cavity enabled us to realize strong coupling under electrical carrier injection. In the micropillar cavity with a quality factor of 10 000 and a diameter of 1.9 mu m, a vacuum Rabi splitting of 108 mu eV was observed when an electrically excited QD exciton was tuned through resonance with the fundamental cavity mode by varying the temperature.
