Computational modelling of a graphene Fresnel lens on different substrates

Abstract

Graphene being the thinnest material known has a lot of potential applications in compact systems, where the size and weight are limited. Here we study through computational modelling a graphene based Fresnel zone plate lens. The optical properties of graphene and the focusing response of the lens are studied for the 850 and 1550 nm wavelengths. The lens performance can be tuned by adjusting the Fermi level of graphene and the number of layers. The effects of substrates (such as glass and SiO2/Si) on the performance of graphene lens are also analysed. The result presented can also be used in optimising the performance of other graphene based optical devices, such as scattering from graphene based transparent electrodes.
