摘要
During the fabrication of uniform fiber gratings, the exposure conditions have effects on the reflection and transmission spectral characteristics of gratings. The reflectivity of fiber gratirgs is nonlinear as a function of both the exposure fluency and exposure time. The shorter-wavelength loss, the change of the bandwidth and the shift of the center wavelength are also investigated in this paper.
