设计了一种基于特定周期排列的空气孔和纯二氧化硅的光子晶体光纤，用于色散补偿。通过引入两种不同尺寸的毛细管(用于气孔)，得到了两个同心的核心结构，并且在1550 nm处表现出很高的负色散[-2200ps/(Nm Km)]。此外，还研究了光学测量参数的变化，以评估制造的公差。弯曲对模式特性的影响表明，可以通过调整光纤直径来调谐C波段的相位匹配波长。
A photonic crystal fiber based on a particular periodic arrangement of airholes and pure silica is designed for chromatic dispersion compensation. A two-concentric-core structure is obtained by introducing two different sizes of capillaries (for the airholes) and exhibits very high negative chromatic dispersion [-2200 ps/(nm km) at 1550 nm]. The variation of optogeometric parameters is also investigated to evaluate the tolerance of the fabrication. Finally, the bending influence on the modal characteristics shows that it is possible to tune the phase-matching wavelength over the C band by adjusting the diameter of the fiber.
