Abstract
Compensation for loss by introducing gain media in optical metamaterials was suggested by Ramakrishna and Pendry (Phys. Rev. B, 67, 201101, 2003). In this work, applying finite-difference-time-domain simulations, we analyzed an Au nanorod (AuNR) structure, as well as fishnet nanostructures with varying positioning of the gain medium. Transmittance, reflection and absorption spectra for an AuNR nanostructure incorporating InP quantum dots (QDs) and of a fishnet nanostructure incorporating InAs QDs have shown that despite limitations, results are encouraging in increasing the transmittance upon gain medium incorporation in the passive regime.
