Abstract :
In the paper, we investigate the reflect spectrum and time delay of SNLCFBG by means of the numerical simulation which be used to compensated dispersion and dispersion slope. The counting method of multi-channel numbers about SNLCFBG is proposed using the sampled rate of the NLCFBG. Then, the versatile formula of counting multi-channel number is pre-calculated to out-of-band multi-channel number on the main petal and the first side petal. The value region of chirped parameter and of the SNLCFBG are analyzed. The peaks of reflect spectrum of the SNLCFBG have a relation with modulation degree. Also, we investigate the relation between the sampled rate and multi-channel equilibrium.
