| Abstract: | Using the analysis of substructures, the paper analyses the fiber Bragg gratings' transmission properties, which is that the refractive index takes place a tiny change in some region. At the same time, it also discusses the changeable relationship between transmission spectra and refractive index-shifted. The transmission spectra changes according to the change of refractive index's value, length of region and location. |
