The photon blockade in a three-wave mixing system coupled with a quantum dot

Abstract

In this paper, the photon blockade effect in a three-wave mixing coupling system with a quantum dot has been studied. By using analytical calculation and numerical analysis, we find that both the conventional photon blockade and the unconventional photon blockade effects could be realized in this system in strong-coupling regime just by one driving. Besides, compared with Jaynes-Cummings model, this hybrid system shows other obvious advantages in realizing the photon blockade, like blockading photon of more different frequencies, stronger antibunching effect, and so on. All the results may provide useful theoretical references for the single-photon devices designing by using quantum dot and three-wave mixing system in future experiments and applications.
