we simulate the reflective spectrum of the Sampled Fiber Bragg Grating(SFBG) by using the transfer matrix method and analyze the effects of the index modulation amplitude
duty cycle
sampling period and the length of grating on the reflective spectrum.On this basis
we use apodization function to eliminate the sidelobe disturbance and obtain a better reflective spectrum of an 8-channel SFBG.
