Negative-index metamaterials: second-harmonic generation, Manley–Rowe relations and parametric amplification
Second harmonic generation and optical parametric amplification in negative-index metamaterials (NIMs) are studied. The opposite directions of the wave vector and the Poynting vector in NIMs results in a “backward” phasematching condition, causing significant changes in the Manley– Rowe relations and spatial distributions of the coupled field intensities. It is shown that absorption in NIMs can...

Second harmonic generation and optical parametric amplification in negative-index metamaterials (NIMs) are studied. The opposite directions of the wave vector and the Poynting vector in NIMs results in a ”backward” phase-matching condition, causing significant changes in the Manley-Rowe relations and spatial distributions of the coupled field intensities. It is shown that absorption in NIMs can...
متن کاملTailoring 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
متن کاملCompensating 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...
