| Abstract: | Quantum coherence and interference are introduced briefly,as well as recent theoretical progress.A GaAs/Al_xGa_(1-x)As asymmetric double quantum well structure with Fano-type tunneling induced quantum interference is proposed,wherein a control light beam can be used to suppress quantum interference and modify the propagation of an optical signal.This phenomenon can be used to realize a broadband ultra-fast optical switch. |

| Keywords: | quantum optics optical switch quantum coherence and interference quantum well |
