Fiber Grating Based 64-Channel Interleavers with 25GHz Channel Spacing and Flat-Top Passbands

Abstract:

An interleaver can separate odd and even channels into two signal streams. In this paper, a novel chirp fiber grating with 14cm length is designed by using the layer-peeling algorithm, which can implements the function of a broadband interleaver with 25GHz channel spacing. The interleaver has 64 channels and flat-top passbands, and its channel isolation is above 28.5dB. All passband central wavelengths are suited for ITU standards, moreover, this grating-based interleaver can be manufactured by existing technologies.
