Paper Abstract

An optimization algorithm is proposed for choosing the parameters of a Fourier flat-top interleaver. The requirement for identical response in both the bar and cross states requires that the intensity coupling ratio for the first coupler must be 1:1. The second and third couplers will depend on the linewidth of each channel. Calculations for typical situations are carried out and the insertion loss for input spectra of different linewidths are also investigated for an interleaver optimized for a typical application.
