This paper reviews recent results on impurity free intermixing of GaAs/AlGaAs quantum wells and application of this technique for integration of optoelectronic devices. Silicon dioxide layers created by plasma enhanced chemical vapour deposition and spin on glass layers were used in this study to create interdiffusion. An integrated device of a laser and a waveguide has been demonstrated.
