摘要
该文提出利用光纤光栅来设计光纤光栅Gires-Tournois(G-T)标准具.用传输矩阵法对光纤光栅G-T标准具的光谱特性进行了分析.研究表明,强光栅决定了光纤光栅G-T标准具的反射率和带宽,弱光栅主要影响其时延和色散特性,强弱光栅之间的间隔决定了光纤光栅G-T标准具的自由光谱范围.最后还给出了自由光谱范围为25 GHz的光纤光栅G-T标准具的设计参数.
The fiber grating G-T etalon was designed by the fiber gratings. A transfer matrix method was introduced for analyzing the spectral characters of the fiber grating G-T etalon. The results show that, the reflectivity and bandwidth of the fiber grating G-T etalon was were decided by strong fiber grating, the group delay and dispersion characteristics was affected by weak fiber grating, the free spectra range (FSR) was decided by the interval between weak fiber grating and strong fiber grating. In the late, the parameters of the fiber grating G-T etalon with 25 GHz FSR was provided.
