Theoretical Modeling of Composite Micro- and Nano-Fiber Devices and Electronic Information Application Research

Abstract

With the continuous development of information science and technology, micro- and nano-fiber optic sensing technology has been widely used in the fields of medicine, communication engineering, and environmental monitoring, and fiber optic devices are widely available in the market because of their advantages such as anti-magnetic interference, corrosion resistance, light weight, high sensitivity, and transmission bandwidth. The purpose of this paper is to investigate the intrinsic correlation between micro- and nano-optical fiber devices and electronic information, introduce the fabrication process of micro- and nano-optical fiber, numerical simulations, and corresponding magnetic field experiments, explore the effects of polarization dispersion and polarization-related dissipation on the system, and enhance the sensing characteristics of micro- and nano-optical fiber through experimental design to maximize its functionality. The experimental results show that the refractive index and magnetic field exhibit a linear relationship with correlation coefficients of 0.995 and 0.994, respectively, when the external magnetic field is between 70 Oe and 300 Oe.
