A large-solid-core fiber design comprised by omitting nine air-holes at the center of square-lattice photonic crystal is investigated for the constant air-hole diameter and for the constant pitch length of air-holes. The fiber characteristics are calculated for both structures, and the results are compared. In the calculations, the plane-wave expansion method is used for effective indices, and we utilized the step-index fiber and Gaussian mode profile approximations for obtaining the effective V-number and the effective mode area respectively.
► Large-solid-core square-lattice PCFs with constant hole diameters are investigated.
► Then, PCFs with constant pitch length are investigated numerically.
► The dispersion properties, confinement losses and mode areas are investigated.
