A new method for the analysis of almost-periodic, nonuniform, nonlinear distributed feedback (NLDFB) structures is presented. A grating segmentation technique used for linear DFB devices is combined with the analytic solutions corresponding to a strictly periodic, uniform NLDFB device. The method is demonstrated for tapered, chirped, and phase-shifted structures. New results describing the operation of single- and multiple-phase shifted NLDFB are reported. NLDFB structures with a axially-varying effective Kerr index are also considered
