Abstract

The unrestricted control of circularly polarized (CP) terahertz (THz) waves is important in science and applications, but conventional THz devices suffer from issues of bulky size and low efficiency. Although Pancharatnam–Berry (PB) metasurfaces have shown strong capabilities to control CP waves, transmission-mode PB devices realized in the THz regime are less efficient, limiting their applications in practice. Here, based on Jones matrix analysis, we design a tri-layer structure (thickness of ~λ/5) and experimentally demonstrate that the structure can serve as a highly efficient transmissive meta-atom (relative efficiency of ~90%) to build PB metadevices for manipulating CP THz waves. Two ultrathin THz metadevices are fabricated and experimentally characterized with a z-scan THz imaging system. The first device can realize a photonic spin Hall effect with an experimentally demonstrated relative efficiency of ~90%, whereas the second device can generate a high-quality background-free CP Bessel beam with measured longitudinal and transverse field patterns that exhibit the nondiffracting characteristics of a Bessel beam. All the experimental results are in excellent agreement with full-wave simulations. Our results pave the way to freely manipulate CP THz beams, laying a solid basis for future applications such as biomolecular control and THz signal transportation.

  • The ultrabroad bandwidth of this Pancharatnam-Berry-based generation is in marked contrast to the very narrow bandwidth attainable by implementing Pancharatnam-Berry THz metasurfaces to manipulate post-generated THz radiation.

    “This ultrabroad bandwidth is in marked contrast to the very narrow bandwidth attainable by implementing PB THz metasurfaces to manipulate the post-generated THz radiation209.”

    From Ultrafast terahertz emission from emerging symmetry-broken materials (2023) · cites this paper as [209]

    The Results (High-efficiency PSHE; page unavailable) describe a working frequency band for this PB THz metasurface and report that strong unwanted modes appear outside it. That supports bandwidth-limited manipulation of incident THz waves, but the paper does not establish that the bandwidth attainable by PB THz metasurfaces generally is “very narrow.” (LLM, conf=0.82)

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.
