Abstract :
The sample-chirp sampled Bragg gratings are investigated and the sample-chirp-induced bandwidth spreading mechanism is exposed. The mechanism is different from the grating-chirp-induced bandwidth spreading mechanism. The higher the Fourier component is, the more quickly the linewidth of the corresponding reflection peak increases. The mechanism can be used to equalize the FWHM linewidth of the multiple reflection peaks within the used bandwidth in unchirped sampled Bragg gratings.
