A novel type of sampled fiber Bragg gratings (FBGs) written in polarization-maintaining fiber (PMF) is proposed.The reflection spectrum, time delay, and group velocity dispersion (GVD) of the gratings are analyzed.In addition, the reflection spectrum is optimized by apodization.The scheme of multi-wavelength output based on the gratings is proposed, which could be used as a multi-wavelength polarization filter in the density wavelength division multiplexed (DWDM) system.
