摘要
In this study, the linear, third-order nonlinear and total refractive index (RI) changes of multi-layered quantum dot (MLQD) and multi-layered quantum anti-dot (MLQAD) are calculated with a hydrogenic impurity. Our numerical results indicate that the RI changes are considerably sensitive to the geometrical parameters of systems and the incident optical intensity. It is observed that by changing the incident photon energy, the RI curves corresponding to MLQAD and MLQD are considerably different in shapes and behaviors. Generally, our results show that MLQAD models have very higher RIs than MLQD models. (c) 2013 Elsevier B.V. All rights reserved.
