光纤是光纤陀螺的核心器件之一.光纤的性能参数直接决定光纤陀螺的性能.常规硅芯光纤制造工艺比较成熟,但受限于物理条件,"克尔效应"、"瑞利背向散射效应"、"法拉第效应"和"舒珀效应"影响比较大.近年来,基于光子带隙效应的导光机制与传输特性制成的在空气中传输光线的空芯光子带隙光纤逐渐应用在光纤陀螺制造中.介绍空芯光子带隙光纤的性能特点,尤其是相比常规硅芯光纤的优势;空芯光子带隙光纤的技术发展潜力;展望其在光纤陀螺中的应用前景.%Fiber is the key component of fiber optic gyroscope(FOG). The performance feature is critical to the performance of FOG. The Kerr effect, Rayleigh effect, Faraday effect and Shupe effect are relatively large in conventional silica fiber although the production mechanism of silica fiber is mature. The hollow core photonics bandgap fiber(HCPBG fiber)gives a priority comparing to conventional fiber considering the Kerr effect, Rayleigh effect, Faraday effect and Shupe effect.The key feature of HCPBG fiber is presented, the technology opportunity of HCPBG fiber is proposed, and future development view is shown in the end of the page.
