| 摘 要： | 报道了一种新的光谱测量方法-基于单模光纤Mach-Zehnder干涉仪(FMZI)结构的傅里叶变换光谱分析法。在传统傅里叶变换光谱仪( FTS ) 中，用光纤代替传统光路;用光纤耦合器取代传统分束器;用压电光程调制器取代传统移动镜;从而构建了光纤傅里叶变换光谱仪(FFTS)。利用该FFTS测量了LD在阈值以下的发射光谱并与光栅光谱仪测量结果进行了比较，结果表明测量结果是相互吻合的。初步的实验中由于光程调制有限，光谱分辨率为～7 cm-1,改造光程调制器可进一步提高光谱分辨率，证明了FFTS用于分析光谱的可行性。

| Abstract: | A novel Fourier transform spectrum analyzer based on a single mode fiber Mach-Zehnder interferometer is reported. An optical fiber Fourier transform spectrometer, with bulk optics components replaced by fiber optical components and with the moving mirror replaced by a piezoelectric element fiber stretcher was constructed. The output spectrum of a LD below threshold was measured. Experiment result agrees with that by using grating spectrum analyzer, showing the feasibility of the optic fiber Fourier transform spectrometer for practical spectrum measurement. Spectrum resolution -7cm^-1 was obtained in our experiment. The resolution can be further improved by increasing the maximum optical path difference. |
