Abstract
We theoretically investigate the lateral and rotary light-drag in semiconductor three-level InAs/GaAs double quantum dot molecules. No coherent laser fields are used and the coherence is created by interdot electron tunneling. The effect of interdot electron tunneling on lateral and rotary light-drag is discussed. Moreover, it is shown that applying an incoherent pumping field to the probe transition changes the subluminal to superluminal condition. It is observed that the light polarization state drags opposite and along with the medium motion in superluminal and subluminal propagating regions, respectively.
