[Abstract]:With the development of optical fiber communication technology, optical fiber sensing technology, computer technology and material science and technology, it is urgent to combine new materials, especially nanomaterials with existing technologies, in the big data information age to construct new optical fiber devices. To meet the needs of future big data transmission and signal processing, is attracting more and more researchers. As two kinds of carbon atoms, graphene is a two-dimensional plane arranged in the shape of a monolayer carbon atom honeycomb, and carbon nanotube is a single-layer carbon atom curled and one-dimensional tubular structure, which combines them with optical fiber. Optical fiber sensors coated with carbon nanofilms are used to detect refractive index, gas, humidity, volatile organic compounds and biological parameters. Theoretical and experimental study on their spectral characteristics is the basic work of developing devices. In this paper, four kinds of fiber structures with different characteristics are designed, and their spectral and modulation characteristics are studied. The main research contents are as follows: in chapter 1, the research status of carbon nanotubes and graphene in fiber optic sensing field and the film forming methods of carbon nanomaterials are summarized. In the second chapter, the working principle and theoretical model of Mah-Zendel interferometric optical fiber sensor and Macelson interferometric optical fiber sensor are discussed in detail, and the characteristics of carbon nanotubes and graphene are introduced in detail. The theoretical feasibility of fabricating the sensor in fiber optic sensing, especially in combination with interferometric optical fiber, is demonstrated. In the third chapter, we study the effect of carbon nanotube coating on the optical fiber spectrum, and introduce the fabrication process of the coated carbon nanotube sensor in detail, which is based on the experimental study of the Mach Zendel interferometric optical fiber sensor coated with single wall carbon nanotube film, and the influence of the carbon nanotube film coating on the optical fiber spectrum is explored. The temperature and refractive index sensing characteristics are studied experimentally. In the fourth chapter, the experimental study on the Mach Zendel interferometric optical fiber sensor coated with graphene film is carried out, and the temperature and refractive index sensing characteristics of the fiber optic sensor are studied experimentally. The obtained results are compared with the experimental results of Mach-Zendel interferometric sensor coated with carbon nanotubes. In chapter 5, two different kinds of carbon nano-film McLherson interferometric optical fiber sensors are studied, and the temperature and refractive index sensing characteristics of two different carbon nano-films on McLerson interferometric optical fiber sensors are studied.
