Metamaterials with low loss and gain
28 Jan 2010 | Online Presentations | Contributor(s): Mikhail A. Noginov
Optical loss caused by absorption in metal and a need for active control are among the major challenges of plasmonic metamaterials. Both can be addressed by utilizing optical gain. Recent efforts aimed at the reduction of loss and the stimulated emission in nanoplasmonic systems with gain will be …

Conquering Surface Plasmon Resonance Loss in Metallic Nanostructures
16 Oct 2007 | Online Presentations | Contributor(s): Mikhail A. Noginov
We have observed the compensation of loss in metal by gain in
dielectric in the mixture of Ag aggregate and rhodamine 6G dye. The
demonstrated six-fold enhancement of the Rayleigh scattering is the
evidence of the enhancement of the localized surface plasmon (SP)
resonance. In the attenuated …

Random Lasers
19 May 2006 | Online Presentations | Contributor(s): Mikhail A. Noginov
Random lasers are the simplest sources of stimulated
emission without cavity, with the feedback provided by
scattering in a gain medium. First proposed in the late
60’s, random lasers have grown to a large research field.
This lecture reviews the state of the art of random lasers,
provides …
