Toward Plasmonic UC-PBG Structures based SWCNTs for Optoelectronics Applications

Abstract

In this paper, the possibility of performing UC-PBG layers that is constructed from a forest of Single Wall Carbon Nanotubes (SWCNT) are aligned vertically on a thin flat film of quartz is studied. Such study is concerned in plasmonic optoelectronic applications in the visible regime. The study is conducted to the numerical simulations based Finite Element Method (FEM), then, compared with measurements. Remarkable benchmarks are found in the performance of the proposed UC-PBG which can be summarized as: 1- excellent ability of focusing the light over a wide range of the visible bands, 2- low effective losses, 3- a miniaturized sizeof the numerical a preacher, 4- no spherical apparition due to the flat geometry. It is found the proposed UC-PBG shows an effective refractive indexvaries from 10 to 20 in Lorentz-Drude manner. The maximum induced power of the proposed UC-PBG is found to be around 450 nm. Nevertheless, the size of the proposed UC-PBG layer is 200nm×200nm. Finally, the obtained results are compared to another numerical analysis based on Finite Integral Technique (FIT). Excellent agreements are found between the two invoked numerical methods.
