摘要
针对光纤偏振随机偏转的问题,提出了一种受激布里渊散射瞬时频率测量技术的优化方案。对比分析了单模光纤和保偏光纤用于实现受激布里渊散射瞬时频率测量的特性差异。实验结果表明:与单模光纤相比,保偏光纤中的偏振随机偏转现象得到有效抑制,测量系统的频率分辨率由225 MHz提高至90 MHz。
Abstract
To address the problem of random polarization deflection in fibers, we propose an optimization method for instantaneous frequency measurements based on stimulated Brillouin scattering. The feature difference is analyzed by comparing how a single-mode fiber and a polarization-maintaining fiber affect the realization of instantaneous frequency measurements based on stimulated Brillouin scattering. The experimental results show that random polarization deflection is well suppressed in the polarization-maintaining fiber compared with that in the single-mode fiber. Further, the frequency resolution of the measurement system with the polarization-maintaining fiber is improved from 225 MHz to 90 MHz.
