摘要：
The group velocity of light is investigated in a hybrid nanostructure comprised of semiconductor quantum dot (SQD) and metal nanoparticle (MNP). In the presence of MNP, the hybrid absorption of the system can be eliminated and forms a broad transparency window even though related dipole transition is not forbidden. Owing to the presence of MNP, there is the formation of the steep dispersion at the transparency regime, thus, the controllable group velocity of light can be implemented. The group velocity of light is changed from subluminal to superluminal via adjusting the inter-particle distance between SQD and MNP. (C) 2012 Elsevier B.V. Open access under CC BY-NC-ND license.
