| Abstract: | A cascade-type three-level system of GaAs/AlGaAs multiple quantum wells (MQWs) is constructed by using biexciton coherence in the transient optical response. Then, we theoretically and numerically study the system with Maxwell–Schrödinger equations to obtain the generated three-wave mixing (TWM) field. By means of appropriately adjusting the strength of the control filed and the propagation length in the MQWs sample, the maximum efficiency of the generated TWM field can be achieved at η ≈ 80%. |
