Abstract
In this paper, we propose and demonstrate that two dark polaritons can be generated in a microcavity that several periods of asymmetric triple-quantum wells are embedded in. They are created by the intracavity coherent effects based on tunneling induced transparency and can be switched by using an external laser. The group time delay of this system is calculated to show the slow dark polaritons. The results have potential applications in all-optical switching and buffering in nano-scale.
