The properties of electron transport through an effective closed three-level structure in an asymmetric double quantum dot system are studied. It is demonstrated that the relative phase between two laser fields can strongly modulate the current through the system, which is similar to the magnetic flux controlled coherent transport in an Aharnov-Bohm interferometer. Two different transport regimes are considered, one is the regime of the chemical potential μR of the right lead between the ground state Ε2 and the excited state Ε3 of the right dot, the other is the regime of &m...
