摘要
It is shown that light transfer between two evanescently coupled optical waveguides can be interrupted when strong interaction with a third waveguide is induced. In the strong-interaction regime the transfer can be reactivated upon proper detuning of the waveguide propagation constants. These phenomena can be easily understood using the analog of Autler-Townes splitting and electromagnetically induced transparency from atomic physics. Experimental demonstration is provided using photoinduced reconfigurable waveguides.
