“…Instead of adjusting the length and width of the fiber core by increasing or decreasing the number of air holes, the structure designed by the arrangement and combination of air holes, which restricts the energy in the center and forms an elliptical mode field, belongs to the elliptical fiber core [9,[11][12][13][14][15][16][17][18][19][20]. Elliptical fiber cores are generally composed of all-circular air hole arrangements [15], all-elliptical air hole arrangements [17], or a combination of circular and elliptical air holes [18] to limit energy in the fiber core.…”

An exceptionally high-performance, high-birefringent photonic crystal fiber (PCF) is meticulously designed. The core design features a unique arrangement in which the central row of circular air holes is substituted by three rows of smaller circular holes. Subsequently, the middle row is adjusted to achieve various rectangular mode field configurations. With the optimized structure parameters, the birefringence of the PCF can reach 3.57 × 10−2 at a wavelength of 1.55 μm. The confinement loss is as low as 8.4 × 10−6 dB/m. The nonlinear coefficient is up to 41 W−1·km−1. The dispersion is relatively flat within the range from 1.3 μm to 1.9 μm. These remarkable characteristics render the proposed PCF a strong candidate for applications in polarization preservation, dispersion compensation, wideband supercontinuum generation, and other related fields.
