Abstract

By theoretic analysis of the interleaved sampled fiber Bragg gratings (ISFBG),the refractive index modulation expression of the ISFBG is deduced.It shows that the ISFBG can be equivalent to a conventional sample fiber Bragg grating.The interleaving technique makes it available that low refractive index modulation results in more channels with almost identical reflectivity.For the first time,two SFBG are interleaved in a fiber and a 10channels dispersion compensator is fabricated with almost identical reflectivity.The group time delay ripples of each channel are almost less than 20 ps.
