Compensating losses in negative-index metamaterials by optical parametric amplification.
نویسندگان
چکیده
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 entangled pairs of left- and right-handed counterpropagating photons.

متن کاملNegative-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...
