Abstract
The study of nonlinear optical effects in semiconductor multi quantum well (MQW) subbands and the related applications is a subject of current interest. Greatly enhanced second order nonlinearities, as compared to those in bulk materials, have been observed by different groups. Recently third order nonlinear effects were probed: via the DC Kerr effect(1), where very large enhancement ratios over bulk values were observed, and using a four wave mixing scheme(2) to measure a large χ(3), all in GaAs/AlGaAs superlattices.
