摘要：

In this paper, we present experimental results which demonstrate that quantum-well intermixing techniques can be used to modulate the magnitude of the second-order nonlinear coefficient chi((2)). Impurity-free vacancy disordering with SiO2 and Ga2O3 caps was used to modulate the position of the band edge and hence, the magnitude of lambda(eff)((2)). Using a coupled quantum-well structure we were able to demonstrate modulation of the d(33) tensor components associated with the asymmetric structure and of the d(14) component associated with the bulk crystal structure.
