The coherent population trapping effect in double tunnel-coupled quantum wells is analyzed. One of two quantum wells interacts with the two-frequency laser radiation and low-frequency field, thus forming a closed contour of excitation. It is possible to control the excited level population in such a scheme of excitation by changing relative phases of the fields in the coherent population trapping state. The quantum well is bound to the other quantum well by tunnel coupling of the excited levels, therefore the population and optical properties of the other quantum well depend on the coherent population trapping state in the first quantum well and can be controlled.
