Chromatic dispersion engineering of photonic waveguide is of great importance for Photonic Integrated Circuit in broad applications, including on-chip CD compensation, supercontinuum generation, Kerr-comb generation, micro resonator and mode-locked laser. Linear propagation behavior and nonlinear effects of the light wave can be manipulated by engineering CD, in order to manipulate the temporal shape and frequency spectrum. Therefore, agile shapes of dispersion profiles, including typically wideband flat dispersion, are highly desired among various applications. In this study, we demonstrate a novel method for agile dispersion engineering of integrated photonic waveguide. Based on a horizontal double-slot structure, we obtained agile dispersion shapes, including broadband low dispersion, constant dispersion and slope-maintained linear dispersion. The proposed inverse design method is objectively-motivated and automation-supported. Dispersion in the range of 0–1.5 ps/(nm·km) for 861-nm bandwidth has been achieved, which shows superior performance for broadband low dispersion. Numerical simulation of the Kerr frequency comb was carried out utilizing the obtained dispersion shapes and a comb spectrum for 1068-nm bandwidth with a 20-dB power variation was generated. Significant potential for integrated photonic design automation can be expected.

Abstract Optical communication systems represent the backbone of modern long-haul communication networks. Nonlinear impairments such as the Kerr effect pose threat and deteriorate transmission in long-haul optical communication systems. At high launch powers, nonlinear effects become more important and their compensation is entailed to improve the transmission performance. In this paper, one of the major nonlinear effects of four waves mixing (FWM) is addressed using a theoretical model and validated through simulation in Optisystem. Two mechanisms with and without dispersion variation are investigated. The impact of FWM is investigated in terms of various values of launch power. The transmission performances of the proposed model are evaluated on the basis of bit error rate, optical signal to noise ratio, and quality factor using key parameters of effective area, nonlinear refractive index, nonlinear dispersion, and linear dispersion.
