摘要

    摘要
  • 摘要: 深入研究了线双折射光栅中透射光偏振特性的演变过程。采用耦合模理论和琼斯矩阵分析了传输距离、双折射大小、入射起偏态等因素对透射光偏振特性的影响，并利用邦加球中描绘了偏振态的演变趋势。结果表明：光栅中的线双折射和传输距离会改变传输光的偏振态，偏振态的波长相关曲线会随传输距离和线双折射的增大而不断扩展，入射起偏态的不同并不改变偏振态的拓展趋势。同时，第一斯托克斯参量与偏振相关损耗在峰值波长点上存在对应关系，两者幅值均与线双折射呈单调递增关系，可应用于传感测量。
    Abstract: Polarization properties of gratings are used to develop new types of fiber Bragg grating (FBG)-based sensors. The evolutions of states of polarization (SOPs) of transmitted light in linear birefringence gratings were studied based on Jones matrix and coupled mode theory, and they were plotted on Poincare sphere. The effects of transmitted length, linear birefringence value and incident SOPs on PDL, the first normalized Stokes parameter and the evolutions of SOPs were discussed. The results show that the SOPs of transmitted light change with linear birefringence value and grating length, and the SOPs relative curves of different wavelengths spread gradually with the increasing grating lengths or birefringence values. The wavelength point of maximum amplitude of the first normalized Stokes parameter is the same as that of polarization-dependent loss, both increase monotonously with birefringence value, which could be used for sensor measurement.
