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...
