Abstract

We have studied for the first time the optical properties of GaAs/Al_xGa_1-xAsAs multiple quantum wells (MQWs) grown on Si and Ge substrates and InyGai-yAs/GaAs strained layer MQWs grown on Si substrates by photoreflectance. These preliminary results show that good quality epilayers from different semiconductors can be grown on non-polar substrates indicating the possibility of new device materials besides their importance in fundamental research. The experimental data were compared with calculations based on envelope-function approximation and fit to third-derivative functional form of reflectance modulation theory.
