【Abstract】 The relations and simulating graphs between the 3 dB bandwidth, peak value, dispersion at λ\-p and sidelobe suppression of the reflection spectrum of linear chirped fiber grating and the chirp value of the grating are given by solving coupled mode equations using the transfer matrix method. In addition, a optimized chirp value range for practical dispersion compensator is obtained by analyzing the simulating graphs.更多还原
