As the channel-space of the comb filter based on chirped sampled fiber Bragg grating and phase shift is not accurate and the multi-channel is unable to channel the standard frequency, we discussed and calculated the error between theory and practice, which has been verified by simulation. Then a compensation method by introducing phase shift between the samples was proposed, and a 100 channel comb filter with accurate 40 GHz channel-spacing was simulated, which lays a good foundation for fabricating comb filters with accurate transmission peak in the future.
