• Semiconductor quantum well
• Relative phase
• Gain and absorption
• Loss-free propagation

We study the propagation effects of the phase-controlled infrared-light pulses in semiconductor quantum-well (QW) heterostructures under realistic experimental conditions. By numerically solving the coupled Bloch-Maxwell equations for electrons and fields simultaneously on numerical grids in time and space, we show that the propagation dynamics can be dramatically modified by varying the relative phase of the applied fields. This opens up the possibility to study optimal control of light propagation in the QW solid materials.
