Abstract: | In a three-level asymmetric semiconductor quantum well system, owing to the effects that result from the incoherent pumping fields, the probe absorption of probe field can be effectively controlled. The result is achieved by applying the two incoherent pumping fields, so it is different from the conventional way in ordinary laser-driven schemes that coherent driving fields are necessary to control the probe absorption. Otherwise, our study is much more practical than its atomic counterpart due to its flexible design and the controllable interference strength. Thus, it may provide some new possibilities for technological applications in optoelectronics and solid-state quantum information science. |
