Four-wave mixing, quantum control and compensating losses in doped negative-index photonic metamaterials
arXiv:0708.0201 · doi:10.1364/OL.32.003044
Abstract
The possibility of compensating absorption in negative-index metatamterials (NIMs) doped by resonant nonlinear-optical centers is shown. The role of quantum interference and extraordinary properties of four-wave parametric amplification of counter-propagating electromagnetic waves in NIMs are discussed.
