Nonlinear characteristics of fused silica,solid-core photonic crystal fibers (PCFs) with a square array of air holes are studied numerically. We present a novel design that emphasizes the difference in air holediameters in the photonic cladding. These PCFs have the advantages offlat dispersion, high nonlinearity, and low attenuation. Based on simulation results, three optimal structures, denoted#F1, #F2, and #F3,havinganomalous and all-normal dispersions in the near-infrared range are selected to investigate characteristic propertiesat the pump wavelength. Such PCFs open up many possibilities for nonlinear optical applications, especially supercontinuum generation.Keywords: Attenuation; Chromatic dispersion; Different air holediameters; Nonlinear coefficient; Square photonic crystal fiber.DOI: https://doi.org/10.37569/DalatUniversity.13.1.1017(2023)Article type: (peer-reviewed) Full-length research articleCopyright © 2022 The author(s).
