摘要：

We report the first observation of second harmonic generation associated with intersubband transitions in AlInAs/GaInAs quantum wells. The measured second order susceptibility in our new asymmetric coupled well structure lattice matched to InP is 4.8 X 10(-8) m/V, about 100 times larger than bulk values in InP, GaAs, and InAs.
