| 摘 要： | 用传输矩阵法对取样均匀光纤Bragg光栅进行了理论分析,并依据此方法对取样光栅的反射谱进行了数值仿真.研究表明:随着光栅长度的增加和采样率、折射率调制深度的减少,反射峰的均匀性得到了改善,旁瓣的反射率变小,带宽明显变窄,而反射峰间隔保持不变.反射峰的间隔由光栅周期决定,与采样率无关.基于取样光栅的独特反射谱特性,对其作...

| Abstract: | The sampled uniform fiber Bragg gratings are theoretically analyzed and numerically simulated with the transfer matrix method.The study shows that with the increase of grating length and the decrease of sampling rate and refractive index modulation depth,the uniformity of reflective peak is improved.The reflectance of the side lobes is decreased slightly and the band width is obviously narrowed but the interval between two reflective peaks is maintained constant.The interval between reflective peaks is dete... |
