Research Onthe Properties Of Devices Based On Graphene Waveguide

Optical waveguide is of high importance as a component of integrated optics, which has broad application prospects in optical communications, optical information processing fields and so on. The research of metamaterials has great significance to the promotion of surface plasmon optics, waveguide devices, slow optical waveguide and ultra-large scale integrated circuits. The bandwidth of existing bulky optical elements is narrow and the loss is large, these disadvantages have become an obstacle limiting the scope of its application. Based on the surface plasmon of Graphenemetamaterials,the waveguide transmission modal size has a height restriction with broadband and low loss features, confining processing the optics in the sub-wavelength range. Therefore, graphenemetamaterials surface plasmon waveguide devices and the slow optical waveguide is a major task for future research. This project will analyze the graphene surface plasmon excitation mode; carrying on a thorough and meticulous research focus on the optical and electrical properties of the graphenemetamaterials waveguide; acquiring the absorption mode and loss property of waveguide devices based on graphenemetamaterials;designing and optimizing slow optical waveguide micro-structure based on the graphene surface plasmon which aimed at low dispersion, high quality factor and long-range. This project will promote the basic and applied research of graphene waveguide devices, laying original foundation for implementing the independent manufacturing technology for graphene waveguide devices. The results of prospective studies will exert a positive and practical impact on not only nano-optoelectronics research, but micro-structural devices constructed by graphenemetamaterials as well.This paper relates to nano-metal microstructure surface plasma physics and classical electromagnetic theory, the mechanism of the interaction between light and matter, has important academic value, for the purpose of the application to develop new nano-photonic devices, will greatly promote the development of nanophotonics, which has broad application prospects. The implementation of this projectcan inspire deep grasp and solve basic nanophotonicsquasiparticles, control and coupling problems, promote the development of nano-photonics based optical waveguide devices and other devices.
