Design of Sampled Fiber Bragg Grating Comb Filter

Abstract

This article based on the theoretical basis of sampled fiber grating, using transfer matrix method to analyse sampled fiber grating, and the analysed the spectrum of sampled fiber grating, and studied sampled fiber grating filter properties. by adjusting the parameters of sampling grating such as: the length of the grating, grating period, duty ratio ( sampling rate) and other parameters, to construct 6 comb filter, and finally come to sampled fiber grating filter preparation method and process in the theory, analysed the application of sampled fiber grating filter in some optical fiber communication fields.
