[Abstract]:Photonic crystal fiber (PCF) has attracted great interest in the field of optoelectronic devices for optical communication because of its flexible structure design and unique light-guiding principle. By designing the structure of photonic crystal fiber (PCF) or filling its cladding hole with metal and other materials, the performance of PCF can be optimized and its application scope can be greatly expanded. Quartz glass is a kind of material with very low loss in optical communication band and easy to pull to make special optical fiber. In this paper, three kinds of rectangular arrangement photonic crystal fibers with quartz air holes are designed by using finite element method. These optical fibers have excellent performance in optical communication band, which is expected to provide some reference or theoretical guidance for the development of new photonic devices. The main contents of this paper are as follows: firstly, the basic theory, preparation method, basic characteristics, research status and application prospect of photonic crystal fiber are reviewed. Secondly, based on Maxwell's equations, the waveguide theory and numerical simulation method of optical propagation in photonic crystal fiber are analyzed. A photonic crystal fiber with elliptical pores and rectangular arrangement is designed. The birefringence and dispersion characteristics of photonic crystal fiber are numerically simulated and analyzed. The zero dispersion wavelength is adjusted to the optical communication band and the birefringence is obtained. Thirdly, a selective gold filled photonic crystal fiber is designed. The principle of surface plasma excitation in the metal-filled fiber is introduced, and good polarization filtering characteristics are obtained in the communication band by adjusting the parameters. Finally, a single polarization single mode photonic crystal fiber with a rectangular pore array is designed. The finite element method is used to simulate it. By adjusting the parameters, a better single-polarization single-mode operation characteristic is obtained at the low loss wavelength of 1.55 渭 m for optical communication.
