This special apodized FBG was designed by the particle swarm optimization algorithm. Compared with conventional apodized FBG, the special apodized FBG presented was more robust in the flat-top pass-band characteristic even if the strength of grating is very week. This technology is very interesting in designing the filter for wavelength division multiplexing system.展开更多

The experiment shows that the maximum DGD monitoring range is widened up to ~6ps using band-pass filter. At the same time, DOP sensitivity has a little change. The experimental results are in accordance with the numerical ones.展开更多
