摘要：
Second-harmonic generation (SHG) from semiconductor quantum-well (QW) structures has recently attracted a great deal of research interest. In this letter we present a study of SHG in AlGaAs/GaAs QWs based on heavy-hole/light-hole intervalence subband transitions. The enhancement of the SHG efficiency over bulk material is discussed. Both the sign and the magnitude of the second-order susceptibility of the well may be controlled; in this fashion, we demonstrate how long-range quasiphase matching of the SHG is then possible.
