Аннотация: The feasibilities and specific features of coherent nonlinear-optical energy transfer from control fields to a negativephase signal are studied, and they are found to stem from the backwardness of electromagnetic waves inherent to negative-index metamaterials. Plasmonic metamaterials that possess negative group velocity for light waves promise a revolutionary breakthrough in nanophotonics. However, strong absorption inherent to such metaldielectric nanocomposites imposes severe limitations on the majority of such applications. Herein we show the feasibility and discuss different nonlinear-optical techniques of compensating such losses, producing transparency, amplification and even generation of negative-phase light waves in originally strongly absorbing microscopic samples of plasmonic metal-dielectric nanostructured composites. © 2009 SPIE.
