Experiments on second- and third-harmonic generation from magnetic metamaterials
Open accessAbstract
Photonic metamaterials could provide optical nonlinearities far exceeding those of natural substances due to the combined action of (magnetic) resonances and local-field enhancements. Here, we present our experiments on second- and third-harmonic generation from magnetic metamaterials composed of nanoscale gold split-ring resonators and from control samples for excitation with 170-fs pulses centered at 1.5-microm wavelength. The strongest nonlinear signals are found for resonances with magnetic-dipole character.

For the noncentrosymmetric U-shaped split-ring resonator, experimental results with second harmonic and THz generation revealed that the effective tensor element dominates and is enhanced by orders of magnitude.
“Experimental results with both second harmonic198,199 and THz generation200,204 revealed that the effective (configuration shown in Fig. 9c3) dominates and is enhanced by orders of magnitude.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
