• A coherently prepared asymmetric double semiconductor quantum well (QW) is proposed to realize parity-time ( PT ) symmetry. By appropriately tuning the laser fields and the pertinent QW parameters, PT -symmetric optical potentials are obtained by three different methods. Such a coherent QW system is reconfigurable and controllable, and it can generate new approaches of theoretically and experimentally studying PT -symmetric phenomena.
