Abstract

A surface plasma polarization wave variable propagating width wave guide based on graphene comprises a silicon substrate and a silicon dioxide substrate which are overlapped. A step-shaped band protrusion is arranged on the silicon substrate, a step-shaped band groove matched with the step-shaped band protrusion is arranged on the silicon dioxide substrate, the step-shaped protrusion is inserted into the step-shaped band groove, the silicon dioxide substrate is provided with a graphene layer, one pole of a bias voltage source is positioned on the silicon substrate, and the other pole of the bias voltage source is positioned on the graphene. The propagating width of the surface plasma polarization wave variable propagating width wave guide based on graphene varies with the bias voltage through design of widths and the bias voltage in different areas of the silicon substrate. The surface plasma polarization wave variable propagating width wave guide based on graphene can be operated on a plurality of frequency points, is light in weight, convenient to process and easy to integrate, and has a good application prospect.

Description

technical field

[0001] The present invention relates to a surface plasmon polarized wave variable propagation width waveguide realized by graphene, especially the propagation width of the surface plasmon polarized wave variable propagation width waveguide based on graphene can be adjusted by applying different biases voltage to change. Background technique

[0002] Since the discovery of graphene in 2004, it has aroused intense research interest. Ashkan Vakil and Professor Nader Engheta proposed a graphene-based surface plasmon polarized wave (SPP wave) waveguide in 2011 (โ€œTransformation optics using graphene,โ€ Science 332(6035), 1291-1294, 2011). Now, we propose a graphene-based SPP wave variable propagation width waveguide, which not only has the advantages of small graphene SPP wave waveguide loss and adjustable dielectric constant, but also has the ability to adjust its propagation width advantage. Professor G.W.Hanson proposed that the conductivity of graphene can be...
