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 be compensated by backward optical parametric amplification. The possibility of distributed-feedback parametric oscillation with no cavity has been demonstrated. The feasibility of the generation of entangled pairs of left- and right-handed counter-propagating photons is discussed.read more

Criterion for Negative Refraction with Low Optical Losses from a Fundamental Principle of Causality
TL;DR: In this paper, the authors derive a rigorous criterion of negative refraction (left handedness) from the fundamental requirement of causality, which imposes the lower limits on the electric and magnetic losses in the region of the negative refractive index.
