Abstract
We investigated the double-tunneling induced transparency of a quantum dot molecule under coherent excitation and considering the spontaneous exciton decay and pure dephasing as two decoherence channels. Because of the efficient destructive quantum interference established by the tunneling coupling, it is found that the double-tunneling induced transparency can easily be controlled by adjusting the system parameters. Our scheme opens the possibility to control double-tunneling induced transparency with electric gates in optical communications.
