The Parameters Choice of NLCFBG Which Be Used to Compensate the Chromatic Dispersion and Dispersion Slope
In the paper, the limit region of linear chirp coefficient c1 and nonlinear chirp coefficient c2 about NLCFBG (nonlinearly chirped FBG) is analyzed at L=5cm. We make the numerical simulation about the reflection spectrum and time delay of the NCLFBG. Then, the relation between the modulation intensity and linear chirp coefficient c1 of the NLCFBG is studied for the first time. The distortion of time delay curve at different modulation intensity is compared. Then, the other parameter limit region of NLCFBG is analyzed. Finally, we investigate the amount of dots which is used to draw graph of the spectrum character and time delay, and it is found that the graph of the spectrum character and time delay is break off when the amount of dots about graph is too less. Also, we study the reflection spectrum of NLCFBG, when segmentation number M of NLCFBG is less, and, the graph of reflection spectrum of NLCFBG is fuzzy, then, we educe a conclusion which is entirely turn over one idea of former literature.
