摘要

在这项工作中，提出了一种石墨烯基等离子体吸收体，其吸收峰为0.99，在1455和1610 nm波长之间具有宽的半峰全宽(FWHM)。该吸收剂由单层石墨烯组成，单层石墨烯覆盖在金属薄膜上的环形和l形凹槽阵列的纳米结构上。光吸收更多的是由于凹槽中的局部表面等离子体共振，增强了光与石墨烯的相互作用。因此，增强了结构的吸收。我们已经证明，吸收器可以通过改变l形臂的长度和凹槽的深度来调谐。此外，可以在近红外区域产生三个吸收峰并具有三波段吸收器。

Absorption enhancement in tunable graphene based plasmonic absorber

In this work, a graphene based plasmonic absorber with two absorption peaks of 0.99 and a wide full width at half maximum (FWHM) between the wavelengths of 1455 and 1610 nm is presented. The proposed absorber is composed of a single layer of graphene that covers the nanostructure with an array of ring and L-shaped grooves on a metal film. The light absorption is more due to the localized surface plasmons (LSPs) resonance in the grooves that reinforces the interaction of light and graphene. Therefore, the absorption of the structure is enhanced. We have shown that the absorber can be tuned by variation of the L-shaped arms length and grooves depth. Moreover, it is possible to create three absorption peaks and have a triple-band absorber in the near-infrared region.
