Photonic quasicrystals are of particular interest for waveguiding applications because of their beneficial advantages over conventional photonic crystals, such as higher-order rotational symmetry and more isotropic Brillouin zone. In this work, by use of a 12-fold symmetric photonic quasicrystal lattice and an optofluidic infiltration approach, we sought to design a hollow-core fiber for telecom C band operation. The simulation results demonstrate a wide flat dispersion range around the zero-dispersion wavelength of 1550 nm and an ultralow confinement loss of 2.6 × 10^-7 dB/m, whereas the maximum effective mode area attained in the simulations is approximately 5.5 μm².

光子准晶体在波导应用中特别受关注，因为它们比常规光子晶体具有更高的优势，例如更高阶的旋转对称性和更各向同性的布里渊区。在这项工作中，通过使用12倍对称光子准晶格和光流体渗透方法，我们试图设计一种用于电信C波段操作的空心光纤。仿真结果表明1550nm的零色散波长和2.6×10超低限制损耗围绕宽扁分散范围^-7分贝/米，而在模拟获得的最大有效模场面积为约5.5微米²。
