FIG. 1.

The schematic illustration of the bulk fishnet metamaterial. (a) Bulk fishnet metamaterial with four-layer metallic fishnet structure, the yellow area indicates the unit cell. (b) The unit symbols for the fishnet metamaterial with , , , , and . Note that the gap between adjacent metal layers is when the stackable unit is cascaded to a multilayer structure.

FIG. 2.

Transmission spectra of the ten-layer fishnet metamaterial with and without gain. The reference data are obtained with the same gain , but at an assumed emission wavelength for the active quantum dots. The inset shows the gain profile of PbS quantum dots.
