In this paper, we propose a method to design the poling pattern of periodically poled lithium niobate (PPLN) devices according to a target spectral response of the selected nonlinear interaction. This method combines a discrete layer peeling algorithm with the deleted-reversal method. The main advantages and limitations of the proposed method in terms of fabrication feasibility of the resulting poling patterns are discussed. The effectiveness of the proposed method is shown by designing PPLNs with two different types of spectral responses: quasi-rectangular bandpass filtering and multichannel filtering. We experimentally demonstrate the method by designing and producing a PPLN which allows performing wavelength conversion within a spectral response approximately given by a 400 GHz quasi-rectangular filter.
