Compensating losses in negative-index metamaterials by optical parametric amplification

Compensating losses in negative-index metamaterials by optical parametric amplification.

Optical parametric amplification controlled by the auxiliary electromagnetic field enables transparency, amplification, and oscillation with no cavity in strongly absorbing negative-index metamaterials. The opposite directions of the wave vector and the Poynting vector in such materials result in extraordinary optical properties, including "backward" phase matching and the generation of entangl...

Tailoring transparency of negative-index metamaterials with parametric amplification

The possibility of compensating losses in negative-index metatamterials doped by resonant four-level centers is shown based on quantum interference and extraordinary properties of parametric amplification of counterpropagating electromagnetic waves. ©2007 Optical Society of America OCIS codes: (1904410) Nonlinear optics, parametric processes, (270.1670) Coherent optical effects

Optical negative-index metamaterials

Four-wave mixing, quantum control, and compensating losses in doped negative-index photonic metamaterials.

The possibility of compensating absorption in negative-index metamaterials (NIMs) doped by resonant nonlinear-optical centers is shown. The role of quantum interference and the extraordinary properties of four-wave parametric amplification of counterpropagating electromagnetic waves in NIMs are discussed.

Compensating Losses in Doped Negative-Index Metamaterials via Four-Wave Mixing and Quantum Control

All-optical switching from absorption to amplification and wavelength-selective narrowband filtering are shown possible in doped solids based on parametric amplification and quantum interference. The results are discussed in the context of compensation of losses in negative-index metamaterials. ©2007 Optical Society of America OCIS codes: (270.1670) Coherent optical effects, (1904410) Nonlinear...
