Tailoring the Dispersion of Plasmonic Nanorods To Realize Broadband Optical Meta-Waveplates

Zhao, Yang, Alù, Andrea·2013·Nano Letters

Abstract

The response of optical metasurfaces is usually narrowband, and mechanisms to increase their bandwidth often clash with causality and passivity constraints of materials. Here we are able to theoretically and experimentally demonstrate that broadband, strong polarization conversion and quarter-wave plate functionality may be achieved using a single, ultrathin planar metasurface in the visible regime. Our realized sample is based on interleaved silver nanorods with properly tailored frequency dispersion that introduce an abrupt flat 90° phase shift for orthogonal polarizations over a thickness of few tens of nanometers, achieving achromatic quarter-wave plate behavior covering a good portion of the visible spectrum. Analogous design principles are extended to cover the entire visible spectrum and beyond.

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.
