Static and dynamic phase-dependence of dark resonances and its dispersion features in double tunneling-coupled quantum wells

In this work we study the coherent population trapping in tunneling-coupled quantum wells interacting with optical radiation. The phase sensitive dependence of dark resonance was investigated. We found that destruction as well as restoration of dark resonance of the coherent population trapping is p...

Summary:In this work we study the coherent population trapping in tunneling-coupled quantum wells interacting with optical radiation. The phase sensitive dependence of dark resonance was investigated. We found that destruction as well as restoration of dark resonance of the coherent population trapping is possible in dependence on algebraic sum of the phases of exciting fields. It is shown that the phase variation of exciting fields influences on the character of the absorption and dispersion of the excited fields in a medium with quantum wells. We found some extreme resonance specify of dispersion relatively phase variation. We obtained analytical expression for the light shift in system with closed contour of excitation. The time-modulation of the laser pumping intensity by phase-time modulation is demonstrated.
