Abstract

Motivated by the realization of the Dirac point (DP) with a double-cone structure for optical field in the negative-zero-positive index metamaterial (NZPIM), we make theoretical investigations of the guided modes in the NZPIM waveguide near the DP by using the graphical method. Due to the linear Dirac dispersion, the fundamental mode is absent when the angular frequency is smaller than the DP, while the behaviors of NZPIM waveguide are similar to the conventional dielectric waveguide when the angular frequency is larger than the DP. The unique properties of the guided modes are analogous to the propagation of electron waves in graphene waveguide [Appl. Phys. Lett., 94, 212105 (2009)], corresponding to the classical motion and the Klein tunneling. These results suggest that many exotic phenomena in graphene can be simulated by the relatively simple optical NZPIM.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In a semiconductor DFB structure, gain and loss regions could be tailored by a judicious control of current injection across the active layer.

    “In a semiconductor DFB structure, gain and loss regions could be tailored by a judicious control of current injection across the active layer [101].”

    From Classical simulation of relativistic quantum mechanics in periodic optical structures (2011) · cites this paper as [101]

    The Model section describes an air-core waveguide with negative-zero-positive-index metamaterial cladding, not a semiconductor DFB structure. Searches for current injection, an active layer, and tailored gain and loss found no passage addressing the claim. (LLM, conf=0.76)

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.
