| Abstract: | The theory for comb-filter with fiber gratings is presented with the method of transmission matrix. The spectirum feature of sampled gratings by numerical analysis with equations is elucldated out. It gives theoretical basic for Optimized design of multi-wavelength comb-filter with fiber gratings. This paper enumerates the parameters of 8-wavelength comb-filter with fiber gratings. The method to get different sampling rate by the combination of two same period amplitude moulds is also brought forward. |
