Second harmonic generation in left-handed metamaterials
نویسنده
چکیده
The extraordinary properties of second harmonic generation in negative-index metamaterials, where the Poynting vector and the wavevector have opposite directions are investigated. The ”backward” phase-matching condition results in significant changes in the Manley-Rowe relations and in spatial distributions of the field intensities of the coupled waves. 0 0 z RHM

Second-harmonic generation in nonlinear left-handed metamaterials
We study the second-harmonic generation in left-handed metamaterials with a quadratic nonlinear response. We demonstrate a novel type of the exact phase matching between the backward propagating wave of the fundamental frequency and the forward propagating wave of the second harmonics. We show that this novel parametric process can convert a surface of the left-handed metamaterial into an effec...
متن کاملGiant Goos-Häenchen Shift of a Gaussian Beam Reflected from One-Dimensional Photonic Crystals Containing Left-Handed Lossy Metamaterials
We perform a theoretical investigation on the Goos-Häenchen shift (the lateral shift) in one-dimensional photonic crystals (1DPCs) containing left-handed (LH) metamaterials. The effect was studied by use of a Gaussian beam. We show that the giant lateral displacement is due to the localization of the electromagnetic wave which can be both positive and negative depending on the incidence angle o...
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...
