Enhancement and suppression of surface plasmon resonance in Ag aggregate by optical gain and absorption in surrounding dielectric medium
M. A. Noginov, G. Zhu, V. M. Shalaev +5
We have observed the compensation of loss in metal by gain in interfacing dielectric in the mixture of aggregated silver nanoparticles and rhodamine 6G dye. The demonstrated six-fo…
Negative Refractive Index in Optics of Metal-Dielectric Composites
A. V. Kildishev, W. Cai, U. K. Chettiar +4
Specially designed metal-dielectric composites can have a negative refractive index in the optical range. Specifically, it is shown that arrays of single and paired nanorods can pr…
Negative Index of Refraction in Optical Metamaterials
Vladimir M. Shalaev, Wenshan Cai, Uday Chettiar +4
An array of pairs of parallel gold nanorods is shown to have a negative refractive index n'=-0.3 at the optical communication wavelength of 1.5 micron. This effect results from the…
