摘要
对基于应力、位移、空间角度的多参数可调谐的光纤光栅(FBG)波长调谐进行了理论分析和实验研究。根据推导出的波长调谐公式,数值模拟了光纤光栅波长受应力、位移、空间角度时的多种调谐关系。在模拟分析的基础上,设计了一种基于应力、位移、空间角度的多参数可调谐的光纤光栅波长调谐器,并进行了实验验证。实验表明基于应力、位移的调谐为线性调谐,各光栅调谐线性拟合度均达0.9975以上;基于角度的调谐近似满足正(余)弦调谐。理论分析和实验测量具有良好的一致性。
The basic principles of multi-parameter tunable optical fiber grating wavelength tuner based on stress, displacement, space angle are analyzed and relative experimental researches are performed. According to the tunable formulas derived in detail, a series of numerical simulations about tuning relationships are presented. On the basis of numerical simulations, we design a multi-parameter tunable optical fiber grating wavelength tuner based on stress, displacement, space angle. Then we carry out relative experimental research. Experimental results indicate that the relation of center wavelength tuning with the force and displacement is linear. The linearity of three fiber Bragg grating （FBG） are above 0. 9975. With space angle as a function of the wavelength of FBG, the fitting curves are approximately sine （cosine） relations. And the experimental results match the theoretical analysis perfectly.
