Abstract：
 An optical chirped SBG-based interleaver filter comprising a Sample Bragg grating (SBG), an interface coupled to the SBG for interfacing with a optical fiber system; wherein the chirp of the SBG is strong enough to cause a stop band or pass band overlapping with at least one neighbor stop band or pass band so that the multiple resonant reflection and transmission peaks are produced.
