Abstract

In the paper, some kinds of curve reflection spectrum and time delay of the FBG is analyzed. We make the numerical simulation the spectrum character and time delay about some kinds of FBG. The relation between the modulation intensity and linear chirp coefficient c₁ of the FBG is studied for the first time. The transformation of curve about time delay is compared at different modulation intensity; We investigate the amount of dots which is used to draw graph of the spectrum character and time delay, and which is found that the graph of the spectrum character and time delay is break off when the graph of dots amount is too less. Also, we study the reflection spectrum of the NLCFBG(nonlinearly chirped FBG), when the segment number M of NLCFBG is less, the graph of reflection spectrum of the NLCFBG is fuzz.
