摘要

少模光纤的受激布里渊散射对于分布式温度/应变传感具有重要应用价值. 本文提出一种纤芯折射率呈M型分布的少模光纤, 详细研究了光学模式LP ₀₁和LP ₁₁模式内及模式间的布里渊增益谱. 研究结果表明: LP ₀₁-LP ₁₁模式对的布里渊增益谱中, 其相邻两个布里渊散射峰的频率间隔较宽、增益峰值较大且峰值相差较小. 通过优化光纤结构参数, 提高了基于LP ₀₁-LP ₁₁模式对布里渊增益谱的温度和应变传感性能, 最小误差分别为0.23 ℃和5.67 με. 该研究对探究少模光纤中模式内及模式间的受激布里渊散射特性具有一定的指导意义, 对提升同时温度和应变传感测量的性能具有一定参考价值.

Abstract

Stimulated Brillouin scattering (SBS) in a few-mode fiber (FMF) is of significance for the distributed temperature and strain sensing. An FMF with M-shaped refractive index distribution (M-FMF) is proposed in order to improve the performance of simultaneous temperature and strain sensing based on SBS. Propagation of four optical modes is supported by the M-FMF, so that the Brillouin gain spectrum (BGS) can be obtained by both intra-mode and inter-mode SBS. The BGSs produced by the interactions of LP ₀₁-LP ₀₁mode pair, LP ₀₁-LP ₁₁mode pair, and LP ₁₁-LP ₁₁mode pair are analyzed, respectively. Meanwhile, the temperature and strain sensing performance based on the BGS of LP ₀₁-LP ₁₁mode pair are studied in detail. Considering a common step-index FMF, only one obvious scattering peak is usually present in the BGS obtained from the interaction between different optical mode pairs, therefore, it is inconvenient to achieve multi-parameter sensing measurement. In this paper, the BGS of LP ₀₁-LP ₁₁mode pair has two scattering peaks, which are contributed by the acousto-optic coupling between the acoustic modes L _1n( n= 1, 2) and the optical modes LP ₀₁and LP ₁₁. The two Brillouin scattering peaks have large gain values of 0.1004 m ^–1·W ^–1and 0.0463 m ^–1·W ^–1, respectively. More importantly, the gain difference between two Brillouin scattering peaks is small, and the frequency interval is 75 MHz, which can be applied to simultaneous temperature and strain sensing. The influences of the refractive index and the fiber core radius on the BGS of LP ₀₁-LP ₁₁mode pair are studied. By selecting the optimal structure parameters, we discuss the effect of temperature and strain on the BGS of LP ₀₁-LP ₁₁mode pair. The errors for simultaneous temperature and strain measurement are reduced to 0.23 ℃ and 5.67 με. Compared with other reported results, our obtained temperature and strain sensitivity are high and sensing errors are low in the considered M-FMF. In other words, based on the BGS of LP ₀₁-LP ₁₁mode pair, the performance of temperature and strain sensing are improved in the M-FMF. This work is of great significance for studying intra-mode and inter-mode SBS in an FMF. Moreover, the results also provide a guideline for further improving the performance of simultaneous temperature and strain sensing.
