摘要
基于光纤光栅理论,制作了一种熊猫型保偏光纤光栅,并用实验验证了其温度和轴向应力响应特性,根据实验结果对比分析了温度逐渐升高和轴向应力逐渐增大时功率的变化情况。结果表明,熊猫型保偏光纤光栅在100~550℃高温范围内具有稳定的波长响应特性,其双峰的波长灵敏度分别为14.3pm/℃和14.4pm/℃,线性拟合度均高达99.9%;在0~2.4N范围内,双峰的轴向应力响应灵敏度分别高达1.477nm/N和1.490nm,线性灵敏度均高达99.9%;随着温度和轴向应力的增大,反射光谱对功率变化情况的响应也不相同。该保偏光纤光栅结构简单,所测温度范围较广,且轴向应力敏感系数较大,具有广泛的应用前景。
Based on the theoretical analyses and experimental verification of the temperature and the axial stress response characteristics,apanda-type polarization maintaining fiber grating is fabricated,and according to the experimental results,we comparatively analyze the power variation under the circumstance that the temperature and the axial stressare increased gradually.The experimental results show that the panda-type polarization maintaining fiber grating in high temperature of 100~550 ℃has stable wavelength response characteristics,and its bimodal wavelength sensitivity are 14.3 pm/℃ and 14.4 pm/℃respectively,the linear fitting is as high as 99.9%.Within the scope of 0~2.4 N,the bimodal axial stress response sensitivity is as high as 1.477 nm/N and 1.490 nm/N respectively,and its linear sensitivity is as high as 99.9%.With the increase of temperature and axial stress,the response of the reflection spectrum to the power variation is different.The polarization maintaining fiber grating has the advantages of simple structure,wide temperature range and large axial stress sensitivity coefficient,and has wide application prospects.
