摘　　要：On the basis of the coherence theory a new method is presented to analyze the sampled chirped fiber gratings (SCFG). With this method, more results on the SCFG are obtained, including not only the characteristics of reflectivity, transmission and time delay, but also the simplified reflectivity formula, the channel's number, wavelength spacing and channel's bandwidth. Therefore, this method is more systematic and perfect than the usual transfer matrix method and can well guide the design of the SCFG.On the basis of the coherence theory a new method is presented to analyze the sampled chirped fiber gratings (SCFG).
