Abstract

Abstract Single mode is one of the most practical applications in microwave propagations because of its high mode resolution and low transmission loss. In this paper, the single mode graphene material was implemented in slab waveguide to study the performance and optical properties of graphene material; the parameters that affect these models were found to be the cut-off frequency, attenuation wavenumbers, modes numbers, skin depth, angles incident, and propagation wave numbers. The effectiveness of these factors was simulated and analyzed using MATLAB software program. In this paper, the carriers were generated using nano-graphene; the optical carrier source provided seven carriers with the frequency spacing of 4.9682 GHz. After splitting the carriers using optical demultiplexer, these carriers were modulated independently using optical Quadrature phase shift keying (QPSK) modulators at symbol rate equal to 4.9682 Gsymbol/s; this matches the frequency spacing of the carriers. Under this argument, the total data rate was equal to 2*7*4.9682 Gsymbol/s = 69.5548 Gbit/s, and the total bandwidth was 34.774 GHz. These carriers were found to work in optical communication with high data rate.

利用纳米材料石墨烯在平板波导中产生高数据速率的光载波

摘要单模由于其高模分辨率和低传输损耗，是微波传播中最实用的应用之一。本文将单模石墨烯材料应用于平板波导中，研究了石墨烯材料的性能和光学性能；影响这些模型的参数是截止频率、衰减波数、模数、趋肤深度、入射角和传播波数。利用MATLAB软件对这些因素的有效性进行了仿真分析。在本文中，使用纳米石墨烯生成载体；光载波源提供了频率间隔为4.9682GHz的七个载波。在使用光学解复用器分割载波之后，使用光学正交相移键控（QPSK）调制器以等于4.9682Gsymbol/s的符号速率独立地调制这些载波；这与载波的频率间隔相匹配。在这种情况下，总数据速率等于2*7*4.9682 Gsymbol/s=69.5548 Gbit/s，总带宽为34.774 GHz。发现这些载波在具有高数据速率的光通信中工作。

期刊介绍： The aim of Curved and Layered Structures is to become a premier source of knowledge and a worldwide-recognized platform of research and knowledge exchange for scientists of different disciplinary origins and backgrounds (e.g., civil, mechanical, marine, aerospace engineers and architects). The journal publishes research papers from a broad range of topics and approaches including structural mechanics, computational mechanics, engineering structures, architectural design, wind engineering, aerospace engineering, naval engineering, structural stability, structural dynamics, structural stability/reliability, experimental modeling and smart structures. Therefore, the Journal accepts both theoretical and applied contributions in all subfields of structural mechanics as long as they contribute in a broad sense to the core theme.
