| Abstract: | Relation of optical properties in a uniform FBG vs. its grating parameters and the laser beam engraving conditions is analyzed and the principle and method for designing the uniform FBG used in DWDM system is given. By adopting double exposure technique, with a uniform phase mask and Gaussian laser beam being used, the uniform FBG used in DWDM system is designed and engraved, where, the bandwidth of the main reflection band at -50 dB is about 0.4 nm while the bandwidth at -25 dB is about 0.7 nm. |
