Metamaterials with low loss and gain
28 Jan 2010 | 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...

We have observed the compensation of loss in metal by gain indielectric in the mixture of Ag aggregate and rhodamine 6G dye. Thedemonstrated six-fold enhancement of the Rayleigh scattering is the evidence of the enhancement of the localized surface plasmon (SP) resonance. In the attenuated total...
Random Lasers

Online Presentations | 19 May 2006 | 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...
