Generation of spatiotemporally tailored terahertz wavepackets by nonlinear metasurfaces
Open accessAbstract
The past two decades have witnessed an ever-growing number of emerging applications that utilize terahertz (THz) waves, ranging from advanced biomedical imaging, through novel security applications, fast wireless communications, and new abilities to study and control matter in all of its phases. The development and deployment of these emerging technologies is however held back, due to a substantial lack of simple methods for efficient generation, detection and manipulation of THz waves. Recently it was shown that uniform nonlinear metasurfaces can efficiently generate broadband single-cycle THz pulses. Here we show that judicious engineering of the single-emitters that comprise the metasurface, enables to obtain unprecedented control of the spatiotemporal properties of the emitted THz wavepackets. We specifically demonstrate generation of propagating spatiotemporal quadrupole and few-cycles THz pulses with engineered angular dispersion. Our results place nonlinear metasurfaces as a new promising tool for generating application-tailored THz fields with controlled spatial and temporal characteristics.

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.”
From Ultrafast terahertz emission from emerging symmetry-broken materials (2023) · cites this paper as [204]
The Results sections on terahertz emission and single-cycle Hermite–Gauss wavepackets describe experimental THz generation from split-ring resonators and identify Ayxx as an effective nonlinear-response-tensor element. The paper discusses second-harmonic generation as prior work, but our copy does not report experiments showing that this tensor element dominates or is enhanced by orders of magnitude. The indexed passages have no page numbers. (LLM, conf=0.86)

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.
